DD DDA.
D15 cm
B.

D.
DNone of the above
D
C
Step 1: Volume of the prism = length × width × height.
Step 2: V = l × w × h[Write an equation.]
Step 3: l = Vw × h
Step 4: = 400(8 × 5)[Substitute V = 400, w = 5, and h = 8.]
Step 6: = 40040[Multiply 5 and 8.]
Step 7: = 10 cm[Divide 400 by 40.]
Step 8: The length of the prism is 10 cm.
