Question

What is the surface area of the prism?

A rectangular prism with length of 7 meters, width of 2 meters and height of 4 meters.

Answer 1

What is the height of a rectangular based pyramid with a volume of four hundred fifty cubic meters and base dimensions of fifteen meters and ten meters

Answer 2

The formula is:

2(lw)+2(wh)+2(lh)

Answer 3

l=length
w=width
h=height

Answer 4

ok

Answer 5

im still confused

Answer 6

Why?

Answer 7

so is 27

Answer 8

what do you mean? "so is 27"?

Answer 9

So we know the formula already.

2(7x2)+2(2x4)+2(7x4)
2(14)+2(8)+2(28)
28+16+56=100

Answer 10

Formulas for a rectangular prism:

Volume of Rectangular Prism:
V = lwh
Surface Area of Rectangular Prism:
S = 2(lw + lh + wh)
Space Diagonal of Rectangular Prism: (similar to the distance between 2 points)
d = √(l2 + w2 + h2)

A cube is a special case where l = w = h. So you can find the volume of a cube or surface area of a cube by setting these values equal to each other.
Calculations for a rectangular prism:

1. Given the length, width and height find the volume, surface area and diagonal of a rectangular prism

h, l and w are known; find V, S and d
V = lwh
S = 2(lw + lh + wh)
d = √(l2 + w2 + h2)

2. Given the surface area, length and width find the height, volume and diagonal of a rectangular prism

S, l and w are known; find h, V and d
h = (S - 2lw) / (2l + 2w)
V = lwh
d = √(l2 + w2 + h2)

3. Given the volume, length and width find the height, surface area, and diagonal of a rectangular prism

V, l and w are known; find h, S and d
h = V / lw
S = 2(lw + lh + wh)
d = √(l2 + w2 + h2)

4. Given the diagonal, length and width find the height, volume and surface area of a rectangular prism

d, l and w are known; find h, V and S
h = √(d2 - l2 - w2)
V = lwh
S = 2(lw + lh + wh)

Answer 11

(28) + (16) + (56) add it together.

Answer 12

The rest of you are just stressing this kid out. Lol

Answer 13

so is 1 meter

Answer 14

....

Answer 15

When a meter multiples another meter how much do you get?

Answer 16

Example: 2m * 2m = 4m^2

Answer 17

You got 100. Now input the meters in.

Answer 18

100m^2 ~

Answer 19

idk

Answer 20

Kid. 100m^2 is the answer....

Answer 21

but on this exam only give 4 options 1 meter
3 meters
9 meters
27 meters

Answer 22

~copy and past the whole question WITH choices.~

Answer 23

What is the height of a rectangular based pyramid with a volume of four hundred fifty cubic meters and base dimensions of fifteen meters and ten meters?

1 meter

3 meters

9 meters

twenty-seven meters

Answer 24

...You have two questions... LMAO

Answer 25

no wonder

Answer 26

That's why I put in all possible formulas. Figured he could take the numbers and plug them in

Answer 27

I don't know why, but I get 3 meters for that question~

Answer 28

so, I see 2 exercises there, one on a prism and another on a pyramid
which is this one?

Answer 29

I think the person is now on the second one.

Answer 30

thank you mikeyy so 3 meters

Answer 31

~Keni, let jdoe help you. I'm not so sure with my answer. I gave it a educated guess.

Answer 32

You are decorating a cylindrical hat box to give to your grandmother as a gift. You want to paste family photos onto the curved part of the box. The height of the box is 8 inches and the radius is 7 inches. If none of the photos overlap, what is the area of photographs you need? Use three point one four for pi.

one hundred seventy-five point eight four square inches

three hundred fifty-one point six eight square inches

one thousand two hundred thirty point eight eight square inches

one thousand four hundred six point seven two square inches

Answer 33

can u help me with that one

Answer 34

Keni, please make new questions! This is the most annoying thing for people who are trying to help you.

Answer 35

if you post anew, you'd get more visibility and we can all help and revise each other :)

Answer 36

ok thank you
