It is 2*(7*4 + 4*2 + 2*7) = 100 square cm.

The surface area is 88.
The surface of a rectangular prism would be 60 yards. This is use in math.
Properties of a rectangular prism: * A rectangular prism has a total of 6 surfaces. * Because it is rectangular it will have 4 equal longer edges and 8 equal shorter edges, and so * It will have 4 rectangular faces and 2 square faces, therefore * Total surface area = 2 x square (end ) surface + 4 x rectangular (side) surfaces If we let x = shorter edges (breadth) & y = longer edges (length), and, as area = length x breadth, then * each end (a square surface) will have an area of x2 * each side (rectangular surface) will have an area of xy Thus: Total surface area of the rectangular prism = 2 x end area + 4 x side area = 2x2 + 4xy = 2x(x + 2y) Hope this nswers your question and explains how we arrive at the formula for calculating the total surface area of a rectangular prism.

With a rectangular prism with these dimensions, you'd have 2 sides with an area of 15*5, two sides with an area of 5*4 and two sides with an area of 4*15. The surface area is 15*5+15*5+5*4+5*4+4*15+4*15 = 310.
You need three measures of length to determine the surface area - the length, width and height.

Surface area of a rectangular prism = 2 x (length x width + width x height + height x length → surface area = 2 x (24 in x 4 in + 4 in x 5 in + 5 in x 24 in) = 472 sq in.
