Answer:
A
Step-by-step explanation:
l(l - 2) = 168
Let w = width
Let l = length
Let A = area
w = l - 2
A = l * w
also, A = 168
equating the two values of A
l * w = 168
l * (l - 2) = 168
l^2 - 2l = 168
378 cm^3
V = Bh = l * w * h
since the Base B is 54 (l*w), multiply by 7 to find volume
54 * 7 = 378
The answer is A
