A pyramid has a square base with sides 100 feet long. The original height was 75 feet.
viva [34]

Step-by-step explanation:

<u>Step 1:  Find the volume of the original pyramid</u>

<u />V = a^2*\frac{h}{3}

V=(100)^2*\frac{75}{3}

V=10000*25

V=250000

<u>Step 2:  Find the volume of the cut off</u>

<u />V=(20)^2*\frac{15}{3}

V = 400*5

V=2000

<u>Step 3:  Find the percent that still remains</u>

<u />250000-2000

248000

248000 / 250000

0.992*100

99.2

Answer:  99.2%
