Question

What is the volume of the square pyramid with
base edges 10 in and height 9 in?
190in
270in
300in
420in

Answer 1

Answer:

$300\ in^3$

Step-by-step explanation:

Use formula for the volume of the square pyramid:

$V=\dfrac{1}{3}\cdot \text{Base area}\cdot \text{Height}$

The base is a square with side 10 inches long, so its area is

$\text{Base area}=10^2=100\ in^2$

The height of the pyramid is 9 inches long, so the volume is

$V=\dfrac{1}{3}\cdot 100\cdot 9=300\ in^3$
