7 inches=7/12 ft.
therefore cubic feet of concrete reqd,
=10*15*7/12
=87.50 cubic feet

V = 10 x 15 x (7/12) ft ³
V = (150 x 7) / 12 ft ³
V = 87.5 ft³ is volume of concrete required.

10ft x 15ft x 7/12 ft = 87.5 cubic feet
the inches measurement you just convert to feet

solution:
req'd: vol. (V) of concrete in cu. ft.
given:
length (L) = 10 ft
width (W) = 15 ft
thickness/depth (H) = 7 in. = 7/12 ft
V = LxWxH
V = 10(15)(7/12)
V = 87.5 cu. ft

Volume=V
V=lenght x width x height
V= 10x15x7
V=1050 cubic feet
It's 7th grade math

87.5 CF because it is only 7 inches deep
