Question

If each edge of a cube is increased by 10 cm, then by how much cm the lateral surface area of the cube will increase

Answer 1

Answer:

Hey mate!!!

Let x be the side of the cube..

There the ratio is

$6x {}^{2} \div 6 \times (10 \times x)$

$x \div 10x$

$1 \div 10$

Therefore the the lateral surface area increases by 10 times...
