Answer:
B. l = 5 cm, w = 6.25 cm
Step-by-step explanation:
The equation to find the cubic volume is V = lwh
Let's input the values we do know:
250 = lw(8)
Divide both sides to isolate the l and the w
31.25 = lw
Now we know that l * w has to equal 31.25, so we can use the process of elimination to determine which answer choice is correct.
A. 5 * 6 = 30
B. 5 * 6.25 = 31.25
C. 5.25 * 6 = 31.5
D. 5.5 * 6.25 = 34.375
The values of the length and width multiplied together only equal 31.25 in answer choice B, so B must be correct.
