Answer:
28 units^3
Explanation:
The formula for finding the volume of a rectangular prism is V = lwh or V = bh
l = length
w = width
h = height
b = base
V = volume
Because we are given the base and height we will use the second formula, V =bh.
V = (8/3)(21/2)
Because we are multiplying fractions, you can just multiply across:
V = 168/6
V = 28 units^3
