Since volume is length x width x height, you would need to cube root 27 in order to make all sides equal and follow the rules of a cube. Therefore, the answer would be 3 since 3 x 3 x 3 = 27.
Answer:
w = 3
l = 10
Step-by-step explanation:
l = 4w-2
P = 26cm
P = (l + w) × 2
26 = (4w-2+w) ×2
26 = (4w + w - 2) × 2
26 = ( 5w - 2 ) × 2
26 ÷ 2 = 5w -2
13 = 5w - 2
13 + 2 = 5w
15 = 5w
w = 3
l = 4w - 2
l = (4 × 3) -2
l = 12 - 2
l = 10
