Answer:
3 feet
Step-by-step explanation:
divide 54 by the 6 faces of a cube.

9 is the area of one face
because a square has equal side lengths, the area of a square is calculated by using Area = length x length
A = 9
(find the square root of 9)
9 = 3 x 3

Answer:
h=4
Step-by-step explanation:
a^2 = h^2 + 4
b^2 = h^2 + 64
(2 + 8 )^2 = a^2 + b^2
100 = h^2 + 4 + h^2 + 64
100-68 = 2h^2
32 = h^2
h = 4
