Question

find the following measure for this figure.
(image of a pyramid with height 12 and base edge 10)
volume =
○ 433.3 cubic units
○ 400 cubic units
○ 1200 cubic units

Explanation:

Step1: Identify figure type

The figure is a square pyramid (base edge 10, height 12).

Step2: Calculate base area

Base area $= 10 \times 10 = 100$ square units.

Step3: Apply volume formula

Volume $= \frac{1}{3} \times$ base area $\times$ height $= \frac{1}{3} \times 100 \times 12$.

Step4: Compute result

$\frac{1}{3} \times 100 \times 12 = 400$ cubic units.

Answer:

B. 400 cubic units
