90 cubic inches.
(2 x 3 x 4) + (2 x 3 x 6.5) + (2 x 4 x 6.5) = 24 + 39 + 52 = 115 square inches
A cylinder with a radius of 7in and a length of 3in has a total surface area of about 439.82 square inches.
Total surface area is 439.82 square inches.

Surface area of a rectangular prism is equal to 2LW+2LH+2HW. So for this object: 2*3*4+2*3*8+2*8*4=24+48+64=136 square inches.
It is: 2(3*5)+2(3*8)+2(5*8) = 158 square inches

(2 x 3 x 4) + (2 x 3 x 6.5) + (2 x 4 x 6.5) = 24 + 39 + 52 = 115 square inches
A cylinder with a radius of 7in and a length of 3in has a total surface area of about 439.82 square inches.
Total surface area is 439.82 square inches.
6*9 = 54 square inches
first you multiply each side by 1,000,000 then you find the surface area of a cylinder that has a diameter of 3in and the height of 6in

Base x Height.... The base of a cylinder is a circle. So you first find the area of the circle. pi times the radius squared. (for example, with a cylinder with a radius of 2in and a height of 3in, the area of the base would be about 2 x 2 x 3.14 = 12.56 Then you multiply the area of the base with the height. So going with our example, 12.56 x 3 = 37.68 inches. Think about it this way: The volume of a rectangular prism is length x width x height. The base of a rectangular prism is a rectangle , and to find the area of that is length x width. So it's the area of the base (which is length x width) x the height.
