Question

question 2 of 10
find the volume of the pyramid below.
a. 400 units³
b. 1200 units³
c. 433 units
d. 1300 units³

Explanation:

Step1: Calculate the base area

The base is a square with side length \(s = 10\). The area of a square \(A_{base}=s\times s\), so \(A_{base}=10\times10 = 100\).

Step2: Use the volume formula for a pyramid

The volume formula for a pyramid is \(V=\frac{1}{3}A_{base}h\). Here, \(A_{base} = 100\) and \(h = 12\). Then \(V=\frac{1}{3}\times100\times12\).
First, calculate \(100\times12=1200\). Then \(\frac{1}{3}\times1200 = 400\).

Answer:

A. 400 units³
