The surface area of a cylinder with a radius 2m and 9m height is 138.23m2
The surface area depends on the shape, not just the length of sides.
Yes - as an example, a 4m by 3m by 2m prism has a volume of 4 x 3 x 2 = 24 m3, the same as a 24m by 1m by 1m prism. However, they have different surface areas. The 4m by 3m by 2m has surface area (4 x 3 x 2) + (4 x 2 x 2) + (3 x 2 x 2) = 24 + 16 + 12 = 52 m2. The 24m by 1m by 1m has surface area (24 x 1 x 2) + (24 x 1 x 2) + (1 x 1 x 2) = 48 + 48 + 2 = 98 m2.
Determine the area of one face (2m x 2m = 42m). Multiply by the number of faces on a cube - 6. So, 6 x 42m = 242m total surface area.

Assuming that you are determining the surface area of a rectangle, in order to perform the calculation you would multiply the length (10m) by the width (2m):Surface Area = Length x WidthSurface Area = 10m x 2mSurface Area = 20m^2
32m2 = 2m x 16m(width)Length(a) x width (16m) = 288m2288m2 / 16m = 18m
The Surface area is given by 2(lb+bh+hl) in this case, l=5m b=3m h=2m therefore the Surface area, sa=2(5*3+3*2+2*5) =2(15+6+10) =2(31) sa =62m2
It is: 6*2*2 = 24 square m
The length or the side length would be 12 meters. 2 times 6 times 12 equals 144m3
A rectangle is one of the six faces of a cuboid (a rectangular parallelepiped). The area of a rectangle 4m long and 2m wide is 8m2. Multiply this by the thickness (or depth) of the cuboid to obtain its volume.
surface area = 2 x pi x r x h = 2x22/7x2x10 = 880/7 = 125.7 (approx.)
