Question

I

Answer 1

Answer:

The deep of the sand will be 3.5 feet

Step-by-step explanation:

step 1

Find out the area of the court plus a 10-foot boundary around the  court for safety

$A=(30+10+10)(60+10+10)\\A=(50)(80)\\A=4,000\ ft^2$

step 2

Find the deep of the sand

we know that

The volume of the sand is equal to

$V=Ah$

where

A is the area of the base

h is the height or deep of the sand

substitute the given values

$14,000=(4,000)h$

Solve for h

$h=14,000/4,000=3.5\ ft$
