Answer:
630 cm³
Step-by-step explanation:
The general formula for the volume of a prism is:
V = Bh, where 'B' is the area of the base and 'h' is the height of the prism
The general formula for the volume of a pyramid is:
V = [tex]\frac{1}{3}[/tex]Bh, where 'B' is the area of the base and 'h' is the height of the pyramid
Since the only difference between these two formulas is the pyramid is 1/3 of the size, to find the volume a rectangular prism with the same measurements as a rectangular pyramid for its base and height:
Pyramid = 210 cm³
Prism = 210 x 3 = 630 cm³
