What is the volume of the composite figure?<br> 12in<br> 4 in<br> 3 in.<br> 7 in.
Minchanka [31]

Answer:

Step-by-step explanation:

V_p = b \cdot h \cdot w, where b, h, w are base, height and width respectively.

V_{sp} = \frac{1}{3} \cdot {A_b} \cdot h, where h is the height, and A_b is the area of the base.

First let's calculate the volume of the paralelipiped by the first formula.

V_p = 7 \cdot 4 \cdot 3 = 84 in^2

Then let's find out the height of the pyramid, which is 12 - 4 = 8 in.(See drawing)

Then the area of the base of the square pyramid is simply.

A_r = 3 \cdot 7 = 21 in^2

Now we can find the volume of the pyramid.

V_{sp} = \frac{1}{3} \cdot 21 \cdot 8 = 56 in^3

To find the total volume, let's add both volumes.

V_T = 84 + 56 = 140 in^3
