The volume of the composite figure made of a rectangular and triangular prism is 216 in³
Volume of rectangular prism = length * width * height
Given the following parameters:
l = 6in
w = 6in
h = 4in
Substitute
V = 6 * 6 * 4
V = 144in³
The volume of the triangular prism = 1/3(6*4)*6
The volume of the triangular prism = 72 in³
Hence the volume of the figure = 144in³ + 72 in³
The volume of the figure = 216 in³
Therefore the volume of this figure is 216 in³
