Question

The volume of a prism is 45 yd3. What would change if the volume of the prism were measured in cubic feet?
A.The volume of the prism would decrease.
B.The volume of the prism would increase.
C.The volume of the prism stays the same, but the number representing the volume increases.
D.The volume of the prism stays the same, but the number representing the volume decreases.

Answer 1

wat do you think, suppose you're 6 ft tall, does your height change if you measure it with a inches tape or with a cm tape ?

Answer 2

no i would still be 6 feet tall

Answer 3

Yes, your height stays same, but when u measure it in cm, the number representing your height may increase

Answer 4

ok lets get back to the original question :)

Answer 5

ok

Answer 6

wat do you think the answer is.. remember, volume is just the space inside prism.

Answer 7

c

Answer 8

perfect !!

Answer 9

volume stay same, but the number represting volume increases, cuz 1 yard = 3 feet

Answer 10

can you help me on another one so i can make sure i understand it

Answer 11

sure :)

Answer 12

The volume of a cube is 512 cm3. What would change if the volume of the cube were measured in cubic meters?

Answer 13

tell me wat u think :)
keep this in mind, 100cm = 1 meter

Answer 14

The number of cubic units would decrease

Answer 15

Yes! cuz cm are less than meter.
and volume stays same

Answer 16

ok thanks

Answer 17

do you knw this :-
1 dozen eggs = ?

Answer 18

12

Answer 19

yes :), can u answer me this q :-

i dont understand the q

Answer 21

its okay :) lol i dint phrase it well... forget it :)

Answer 22

ok

Answer 23

:D

Answer 24

how would i workout this q

The rectangular prism shown has a volume of 72 m3. This prism is enlarged using a scale factor of 3.

What is the volume of the enlarged prism?


A. 75 m3

B. 216 m3

C. 648 m3

D. 1944 m3

Answer 25

volume = lbh = 72 --------(1)

Answer 26

when u enlarge it wid a scalefactor of 3, you're multiplying each dimension wid 3. so,

new volume = (3l)(3b)(3h)
=3^3 lbh
=27 x 72
= ?

Answer 27

1944

Answer 28

yes !

Answer 29

=D

Answer 30

:)

Answer 31

Which shows the dimensions of two rectangular prisms that have volumes of 320 mm3 but different surface areas?

A. 16 mm by 5 mm by 4 mm;
5 mm by 4 mm by 16 mm

B. 10 mm by 4 mm by 6 mm;
6 mm by 10 mm by 4 mm

C. 8 mm by 10 mm by 4 mm;
10 mm by 8 mm by 4 mm

D. 8 mm by 10 mm by 4 mm;
20 mm by 8 mm by 2 mm

Answer 32

easy, find the volume and surface area for each of them

Answer 33

to find volume, just multiply given dimensions :
volume = l x b x h

Answer 34

to find surface area, use below formula :-
area = 2(lb + bh + hl)

Answer 35

a

Answer 36

nopes, all A, B, C have same surface area and volumes

Answer 37

only D doesnt have same surface area, eventhough volume is same.
