The masses of two similar plastic boxes are 8.58 kg and 4.29 kg. Given that the first box has a base area of 12.94 m², find the base area of the second box.

i'm guessing it might be 40.

you start with 40 minutes and 8 people to paint a wall. then it asks how many minutes does it take 10 people to paint seven walls.

that means you start with division.

40÷8=5

now you have to multiply that by 10

10×5=50

now you want to multiply the amount of walls by number minutes.

50*7= 150 minutes or 2½hrs

hope this ! -john

i'm pretty sure you meant to write tenth, which refers to decimals. so that would be 6809.20 as you would round down. remember, anything less than five goes down, and anything that is five or higher than five goes up. : )
