Question

Nancy made a solid shape with cubes and cuboids. Choose the correct option to calculate the volume of the entire solid.

• A. Calculate volume of A + B, then B + C + D, then E + D
• B. Calculate volume of A, then B + C + D, then E + D
• C. Calculate volume of A, then B + C + D, then E
• D. Calculate volume of A + B, then B + C + D + A, then E + D

Answer 1

The correct option is C Calculate volume of A, then B + C + D, then E

The volume of the solid can be calculated by multiple ways.
To calculate the volume of entire solids, we have to add up the volume of each part only once.
Hence, we can calcualte volume of part A alone, then we can add up the volume of the bottom cuboid (B + C + D), then finally the volume of part E.
