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

The amount of sand is equivalent to the volume of the sandbox. Volume is L x W x H = v. The volume = 160 feet cubed, or to the 3rd power.

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=
