Scaled up by a factor of 10 implies that its sides are multiplied by 10
Scaled down by a factor of 1/10 applies its sides are divided by 10
Use these above facts to work out the surface area and volume in each condition

Surface area= 2ab+2bc+2ac
Surface area = 2(115)(30)+2(95)(30)+2(95)(115)
Surface area = ..............
