I guest that you mean that every edge of the prism is 10 ft, that is it is a cube of side 10 ft: A cube has 6 faces all the same size ⇒ surface_area = 6 x 10 ft x 10 ft = 600 sq ft.

When the surface area and the volume are the same, the height has a value of one unit. Example based on values given: A=LxW = 25x5 = 125 sq ft. V= LxWxH = 25x5x1 = 125 cu ft. The surface area and the volume have the same value.
Total surface area = (2*pi*radius squared)+(pi*diameter*height)

Volume of a prism = cross section area times height or length 36*4.5 = 162 cubic feet
Volume of prism = Base Area * Length = (1/2 * 10 ft * 1 ft)* 15 ft = 75 cubic ft.
864 ft
The surface area is 46 square feet.

Area of each triangular face = 4*sqrt(3) sq ft = 13.86 sq ft (to 2 dp) Area of each rectangular face = 40 sq ft Total area = 2*13.86 + 3*40 = 147.71 sq ft

2(9*8 + 9*14 + 8*14) = 620 square feet.
