Answer 2

Answer:

Step-by-step explanation:

Let the sides of the cube be 5 units

So lateral surface area of the cube=4×side²=4×5²=4×25=100 sq.unit

If the sides are increased by 50% , then sides become 5+5/2=7.5 unit

So lateral surface area=4×(7.5)²=4×56.25=225.00 sq.unit

So increase in area=225-100

=125 sq.unit

So percentage of increase in area is 125%.

Hope you got it.
