Rectangle Volume: 56 cubic inches
Triangle Volume (Left): 3 cubic inches
Triangle Volume (Right): 3 cubic inches
To get the entire shape's volume, add up all the individual shapes' volume:
56 + 3 + 3 = 62
Overall Volume: 62 cubic inches (assuming I did the math right)
Formula (In case you want to know):
Rectangle (V): Length × Width × Height
Triangle (V): (Base × Height) × 1/2 (or divide by 2, your choice)
If you want to know which side is which (for the length, height, width, etc.), just ask me.
