[2] The units of surface area will be some unit of length squared: in 2, cm 2, m 2, etc. 2 Measure the length of one side. Each side or edge of a cube should, by definition, be equal in length to the others, so you only need to measure one side. WebThe surface area of a cuboid formula = 2 (lw + wh + lh) From the given dimensions, let us take length (l) = 8 units and width (w) = 6 units, and height (h) = 4 units. Therefore, the surface area = 2 { (8 × 6) + (6 × 4) + (8 × 4)} = 2 (48 + 24 + 32) = 2 (104) = 208 square units Answer: The required surface area is 208 square units. pink care bear with rainbow
