Answer:
7.6
Step-by-step explanation:
a^2 + b^2 = c^2
6.5^2 + x^2 = 10^2
42.25 + x^2 = 100
isolate x by subtracting 42.25 on both sides
x^2 = 57.75
square root of 57.75 or 7.6
Answer:
or 
Step-by-step explanation:
The formula for volume is Base * Height * Width; and the formula for area is Base * Height.
This problem mentions the structure is a cube and therefore it is assumed that every wall has the same area. Since there are 6 sides to a cube you divide the total amount of ft which make up this cube to know the area to each wall.
= 2.25 or
per wall
With the area of each wall you can find the base and height:
base * height = area

base =
m
height =
m
since: base=height=width, the width also equals
m
volume =
=
