Answer:
Step-by-step explanation:
Denote the rectangular prism's volume as VR and the volume of the right triangular prism as VT. Given that the rectangular prism's volume exceeds that of the triangular prism by 32 cubic feet, we establish that VR = 32 + VT.
Calculating VR: VR = length * width * height = 6*x*3.
This simplifies to VR = 18x ft³.
For the triangular prism, VT can be calculated as Length * width * Height / 2, yielding VT = (7 * x * 4) / 2.
Thus, VT = 28x / 2, which simplifies to VT = 14x ft³.
Equating VR to 32 + VT allows the substitution: 18x = 32 + (14x).
Now, simplify the equation:
Combine like terms: 18x - 14x = 32.
This results in 4x = 32.
Dividing both sides by 4:
x = 8.
The volume for the rectangular prism comes to 18x, which equals 18*8.
The volume of the rectangular prism calculates to 144 ft³.
The volume for the right triangular prism calculates to 14x, which equals 14*8.
The volume of the right triangular prism calculates to 112 ft³.
