12'5 = 12.4166... feet
The total surface area, of all four walls, floor and ceiling is
2*(12.4166...*12.4166... + 12.4166...*10 + 10*12.4166...)
=2*(154.1736 + 124.1667 + 124.1667) = 2*402.5069 = 805.01 sq feet (to 2 dp)
For the surface area of a rectangular prism (like a non-square room) multiply each number by each other number, add them together and multiply by 2.
A) 12' 5"=149"

Entire surface area of the hemisphere including its base area:- (2*pi*10^2)+(pi*10^2) = 300*pi square units
A cylinder 10 feet high and 5 feet in radius has a surface area of 471.24ft2
The curved surface area is 314.16 square units.
The surface area is 600 sq. inches. The formula for surface area of a cube is 6s^2 where s is the side length. The general surface area formula is 2B+Ph where B is the area of the base, P is the perimeter of the base and h is the height.
Entire surface area: (2*pi*49)+(14*pi*10) = 747.7 square feet
The surface area of a sphere that has a radius of 10 is: 1,260 square units.
