The volume of a cube is s^3
divide x^3 = 185 = 5.69 cm
Perimeter, P = 2*(L + W)
Length, L = 14, Width = x
P = 2*(L + W)
38 = 2*(14 + x).
2*(14 + x) = 38, is the equation used to find x.
Let's go ahead and solve for x, though the question did not ask us to solve it.
14 + x = 38/2
14 + x = 19
x = 19 - 14
x = 5
Width is 5 inches.
So her trainer travels 20miles(using the Pythagoras theorem) while she travels 12+16=36 so the answer is 36-20=16
The volume of the pyramid is 40
.
Explanation
The volume of the pyramid is determined by its base area and the height.
Given that
The base of the pyramid given in the problem is a rectangle
length of the base= 5 cm
breadth of the base=4 cm
base area A= length*breadth(area of rectangle)
=4*5=20 
height of the pyramid h=6 cm
volume of the pyramid=1/3 Ah
=1/3 *20*6=40
Answer: the degree of the angle if that is what you're asking is 257 degrees
