Step-by-step explanation:
Each edge of a cube is increased by 10%.
Formula:
If each edge of cube is increased by x%, then
the percentage increase in its surface area = x + x + (x × x)/100
Total surface area of cube = 6a2
Calculation:
Short Trick:
∴ The percentage increase in its surface area = 10 + 10 + (10 × 10)/100 = 20 + 1 = 21%
Detailed Method:
Let side of cube be 10 m
Total surface area of cube = 6 × 102 = 600 m2
New side of cube = 10 × (110/100) = 11 m
New total surface area of cube = 6 × 112 = 726 m2
Area increased by = 726 - 600 = 126 m2
∴ Area increased by (in %) = (126/600) × 100 = 21%
