Hugo is mixing blue paint with red paint to create purple paint. The ratio of blue to red is 3 to 2.

How many pints of blue paint will he use to create 40 pints of purple paint?

I’m not gonna do that

The correct answer is b

Volume is length times width times height so
20 times 8 times 30 which is 4,800
surface area is ph (p is perimeter of base), h is height.
so perimeter would be length+length+width+width so 20+20+8+8 which is 56. so multiply 56 times 30 which is 1680. hope this !
