Answer:
800 inches³
Explanation:
∵ The volume of each cube is s³
∵ The length of the side is 2 inches
∴ The volume of the cube = 2³ = 8 inches³
∵ The prism consists of 100 cubes
∴ The volume of the prism = 100 × 8 = 800 inches³
Another method:
We divide the number of cubes to form the rectangular prism
5 cubes as a length , 2 cubes as a width and 10 cubes as height
∵ The length of the side of each cube is 2 inches
∴ The length = 5 × 2 = 10 inches
∴ The width = 2 × 2 = 4 inches
∴ The height = 10 × 2 = 20 inches
∵ The volume of the prism = L × W × H
∴ V = 10 × 4 × 20 = 800 inches³
