The Hypotenuse is 10 Meters.
4x + y = 12
Get y by itself
Subtract 4x
y = -4x + 12
Since you know what y is, you can plug the value into the second equation
6x + 2(-4x + 12) = 18
6x - 8x + 24 = 18
-2x = -6
x = 3
Plug the value 3 into x for y = -4x + 12 in order to find y
-4(3) + 12 = y, y = 0
Solution: x = 3, y = 0
The volume formula of a pyramid is:
V =

x length x width x height
The given are
Length = 24 cm, Width = 18 cm, Height = 35 cm
Substitute the values to find the volume
V =

x 24 x 18 x 35
V = 5040 cm³
