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

viva [34]

Step-by-step explanation:

Step 1: Find the volume of the original pyramid

$V = a^2*\frac{h}{3}$

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

$V=10000*25$

$V=250000$

Step 2: Find the volume of the cut off

$V=(20)^2*\frac{15}{3}$

$V = 400*5$

$V=2000$

Step 3: Find the percent that still remains

$250000-2000$

$248000$

$248000 / 250000$

$0.992*100$

$99.2$

Answer: 99.2%
