WebOct 10, 2024 · Academic Mathematics NCERT Class 10. Given: Each edge of a cube is increased by 50 %. To do: To find the percentage increased surface area of the cube. Solution: Let the side of the cube is a. Surface area of cube = 6 a 2. On 50 % increase, New side = 3 2 a. New surface area = 6 ( 3 2 a) 2. = 6 × 9 4 a 2. WebLet the edge of a cube be 100 cm. New edge after increment of 40% = 140 cm. Surface area of a cube before increment in edge = 6 × 100 × 100 = 60000 cm 2. Surface area of a cube after increment in edge = 6 × 140 × 140 = 117600 cm 2. Percentage increase in surface area of a cube = 117600 − 60000 60000 × 100 = 57600 60000 × 100 = 96%.
