Question

The sandbox at the playground is 2 ft tall. The area of the base of the sandbox is 80 square feet. How much sand does it take to fill the sandbox?

Answer 1

(1*80)^2=160 the reason you double it is because the height is 2. So the answer is 160 square feet of sand.

Answer 2

`160\ ft^(3)`

Explanation:

we know that

The volume of the sandbox is equal to

`V=Bh`

where

B is the area of the base of the sandbox

h is the height of the sandbox

we have

`B=80\ ft^(2)`

`h=2\ ft`

substitute

`V=80*2=160\ ft^(3)`
