Answer:
Surface area = 96 m^2
Step-by-step explanation:
Let's cube root the volume to find the length of one side of the cube.
Therefore each side is 4 m.
Surface area of one side = 4x4 = 16
A cube has 6 sides.
Total surface area of the cube = 16*6 = 96 m^2
Answer:
15 inches
Step-by-step explanation:
1. Use the Pythagorean Theorem: a^2+b^2=c^2
You are already given c (the longest side) and one of the legs which could be a or b.
2. Plug the numbers into the formula and square them.
a^2 + 36^2 = 39^2
Squaring the numbers gives you: a^2 + 1,296 = 1,521
3. Subtract 1,296 from both sides and take the square root of the result.
a^2 = 225
= 15
