if 2 cubic feet of sand weigh 90pounds, how much do 5 cubic feet of sand weigh?

Sagot :

if 2 cubic feet weigh 90 punds,
you know that 1 cubic weigh 45 punds
now multiply it by 5, therefore 5 cubic feet of sand weigh 225 punds

2 = 90
1 = 45     //divided by 2
5 = 225   //times 5

Answer:5 cubic feet of sand weigh 225 punds

Well you already know that 2 cubic feet of sand weighs 90 pounds, so 90 ÷ 2 = 45.

Now you know that 1 cubic feet of sand weighs 45 pounds. Now you need to figure out how much 5 cubic feet of sand will weigh. If each cubic feet of sand weighs 45 pounds you just multiply 45 × 5 = 225

So 5 cubic feet of sand will weigh 225 pounds.

Hope that helps you. :-)
