An open topped box has a square base bottom and a height of 7cm If the surface area of the five sides of the box is 165 cm squared find the dimensions of the square base?
4 x h x b + b2 = 165
4 x 7 x b + b2 = 165
28b + b2 = 165
0 = b2 + 28b - 165
using quadratic formula
b = 5

What is the surface area of a cylinder with a height of 0.38 and width of 2.1?
Surface area = Area of rectangular face + Area of top and bottom circles Area of rectangular face = pi * diameter * height Area of top or bottom circle = pi * (diameter)2 / 4 So, Surface area = 3.14 * 2.1 * 0.38 + 2 * 3.14 * (2.1)2 / 4 = 9.43 The total surface area is 9.43, in whatever units you're using (such as inches squared, meters squared, etc.)

Formula for surface area of a pyramid?
The surface area is length times width plus length. Then you find the square root of the width divided by two and then squared. You add this to the height squared plus the width. The width is multiplied by the square root of 1/2 squared plus the height squared.

What is the surface area of a cylinder with 4m in diameter and 6m in height?
The surface area of a (closed) cylinder equals the surface area of both bases (the top and bottom), i.e. pi x radius squared (first base) + pi x radius squared (second base), plus the lateral surface area (the surface area of the curved side), i.e. circumference (pi x diameter) x height. Inserting the numbers: SA = pi x (2 m.) squared + pi x (2 m.) squared + pi x 4 m. x 6 m. = pi x 4 m. squared + pi x 4 m. squared + pi x 24 m. squared = 8 x pi m. squared + 24 x pi m. squared = 32 x pi meters squared.
