How would 350 percent be written as a simplified fraction

Divide by 100. 350/100=3.5 which is 3 and 1/2

It would be 0.350 and convert that into a fraction

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 !
