The total volume of the composite figure is 64 in³.
Volume of a rectangular prism
The volume of a rectangular prism, V = lwh where
- l = length,
- w = width and
- h = height
Volume of horizontal rectangular prism
Since horizontal rectangular prism has a length of eight inches, a width of two inches, and a height of two inches. So,
- l = 8 in,
- w = 2 in and
- h = 2 in.
So, its volume V' = lwh
= 8 in × 2 in × 2in
= 32in³
Volume of vertical rectangular prism
Since the vertical rectangular prism connected at the right end of the other prism has a length of two inches, a width of two inches, and a height of eight inches. So,
- l = 2 in,
- w = 2 in and
- h = 8 in.
So, its volume V" = lwh
= 2 in × 2in × 8 in
= 32 in³
Volume of composite figure
The volume of the composite figure V"' = V' + V"
= 32 in³ + 32 in³
= 64 in³
So, the total volume of the composite figure is 64 in³.
