320 because you added the two numbers to get the total.
Answer:
112in²
Step-by-step explanation:
Formulas: V =
, V = lwh
Sub: v = 
Solve: 32
Sub: v = 4 x 4 x 5
Solve: 80
V = 80 + 32
V = 112
<u>The total volume of the figure is 112in²</u>
Substitution method can be applied in four steps
Step 1:
Solve one of the equations for either <span>x = </span>or y = .
Step 2:
Substitute the solution from step 1 into the other equation.
Step 3:
Solve this new equation.
Step 4:
Solve for the second variable.
hope this helps you!
V = L * W * H
V = 4 * 4 * 8
V = 16 * 8
V = 128 cubic ft
