This is simple pythagoras, its just a²+b²=c². First you find the hypotenuse, which is 97; now you have the equation: x²+72²=97²
x²=9409-5184
x= √4225
x=65
the answer is 65m
The answer I believe would be ninety millionth
No picture so I can’t answer this .
I think u set the two equations equal to eachother then solve for x
Answer:

The volume is 128cm^3
Step-by-step explanation:
Given


Required
Determine an expression for its volume
Find the volume
Volume of a cube is:

Where x represents the length of a side
So, volume of 2 cubes would be:


Solving (b): Volume when x = 4
Substitute 3 for x in 



<em>Hence, the volume is 128cm^3</em>
