A 25 cm cube has all edges with a length of 25 cm. Therefore each face has an area of 25*25 = 625 sq cm. As a cube has 6 faces, the total surface area of the cube is 625*6 = 3750 square centimeters.

In order for an object to qualify as a cube, it must satisfy these properties: * 6 faces (like a die), 12 edges, 8 corners * all it's edges must be equal length * all it's faces have equal area If the area of the cube is 294, then the sum of it's 6 faces' area is 294 So... The area of one face is 294 ÷ 6 = 49 If all it's edges have equal length, then each face is a square. The area of a square is length × length = length = length² = 49 So... the length of one edge is the square root of 49 = 7, -7 Since you are looking for a length, -7 is not an option. The length of the edge is 7

You square the length of each edge and then multiply the result by six. For example, if a cube has edges measuring 3cm, the surface area will be 32 (9) x 6 = 9 x 6 = 54 square units.

150 square centimetres is a measure of area. Assuming it is the total surface area of the cube, the surface area of any one [square] face is 150/6 = 25 sq cm. Consequently, the width and length are sqrt(25) = 5 cm.

ok, so think about it. a cube has 6 sides. The surface area is the area of the surface of all 6 sides combined, so you divide the surface area by 6. This gives you the area of each square on each side. Then square root the answer because the area of a square is the side length squared. Now you have the edge length!

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.
