Question

Find the volume of a pyramid which has a square base of 10 inches and a height of 24 inches

Answer 1

V = 1/3 (area of base ) (hieght)

Answer 2

V = 1/3 (100)(24)

Answer 3

how is it 100?

Answer 4

base is a square with a side length of 10
A = L *W
A = 10*10
A = 100

Answer 5

so 1/3(100)(24)

Answer 6

1/3(2400)

Answer 7

right, keep going

Answer 8

multiplying by 1/3 is same as dividing by 3

Answer 9

800

Answer 10

great!
now dont forget the units

in this case it will be 800 in^3 (or inches cubed)

Answer 14

A right circular cylinder has all of its dimensions multiplied by four. How is its surface area affected?

Answer 15

@Jim766

Answer 16

hold on a second

Answer 17

surface area of a cylinder

2pi(r^2) + 2pi(r)(h) lets say the dimensions are r = 1 and h = 1
2pi(1^2) + 2pi(1)(1) = 4 pi

Answer 18

now let mult each dimension by 4

2pi(4^2) + 2pi(4)(4)

32 pi + 32pi = 64pi

it went from 4 pi to 64 pi

4^3 = 64 so the answer is the surface are would be cubed
