Question

Find the volume of the pyramid to the nearest cubic unit. Use a calculator.

Answer 1

Answer:

64 m³

Step-by-step explanation:

Formula

$\textsf{Volume of a square based pyramid}=\dfrac{1}{3}a^2h$

where:

• a = side length
• h = perpendicular height

Given:

• a = 8 m
• h = 3 m

Substituting the given values into the formula:

$\begin{aligned}\implies \textsf{Volume}& =\dfrac{1}{3} \cdot 8^2 \cdot 3\\\\& = \dfrac{3}{3} \cdot 64\\\\& = 1 \cdot 64\\\\& = 64\:\sf m^3\end{aligned}$

Answer 2

Answer: 64 m^3

Step-by-step explanation:

V=1/3*a^2*h

V = 1/3*64*3

V=64 m^3
