Answer:
Step-by-step explanation:
The area will be increased by 4 times and volume will be increased by 8 times
Area of rectangular prism = 2 (lb+bh +hl)
When sides are doubled, Area = 2 (2l * 2b +2b *2h + 2h*2l)
= 4 * 2 (lb+bh +hl)
Volume of rectangular prism = lbh
When sides are doubled, Volume = 2l * 2h * 2b = 8 lbh

3 15
cross multiply
(3)(x) = (15)(2)
3x = 30
x = 30/3
x = 10
so 2/3 = 10/15.......notice how these are equivalent fractions....that is because proportions are nothing but equivalent fractions
