Answer:
320 cubic cm
Step-by-step explanation:
To answer a prism volume question, also see it as a shape (in this case a triangle) that is very thick.
First step is to calculate the area of the shape. We all know the formula to calculate the area of a triangle: (b x h)/2. And we those two measures. The height of the triangle is b (8 cm), the base of the triangle is a (10 cm).
A = (b * h)/2 = (10 * 8) / 2 = 80 / 2 = 40 sq cm
Then we multiply the base area of the prism by its height to get the total volume. In this case, the height is also known, h = 8 cm.
V = b * h = 40 * 8 = 320 cubic cm
