Answer:
13 1/8ft³
Step-by-step explanation:
Formula for calculating the volume of a prism is base area × height
Volume = Bh where;
B is the base area
h is the height
Since the base of the prism is rectangular in shape, we will find the area of the rectangle to get the base area.
Base area = length×breadth
Base area = 2 1/2ft × 3 1/2ft
Base area = 5/2×7/2
Base area = 35/4ft²
Since height = 1 1/2ft = 3/2ft
Volume of the prism = 35/4×3/2
Volume of the prism = 105/8ft³
As a mixed number will give;
Volume of a prism = 13 1/8ft³
