earth and cement block filling a box weighs 390mlb.the block weigh 2.4times as much as water and earth weighs 1.5times as much as water.water filling the box weighs 2000lb.find the weigh of the cement block.bl?

plz help help help!!!! Show work

The given ratios indicate that the block weighs 1.6 times as much as earth. So, if the block weighs b lbs, then we have

b + 1.6b = 390

Now just find b.

I don't see what the ton of water filling the box has to do with anything. Especially since it weighs less than the earth and cement, and they only weigh 390 lbs.

Sorry it 3900 not 390lb

A gallón of wáter weighs light aun a third lbs.How much does pone anda a fifth gallón weighs?

To find the weight of the cement block, we need to use the information given about the weight of the water, earth, and the relationship between the weight of the cement block and water.

Let's break the problem down step by step:

1. Let's assign variables to the unknown weights. Let's say:
- Weight of the cement block = C
- Weight of the earth = E
- Weight of the water = W

2. From the given information, we know that the weight of the water filling the box is 2000lb. So we have:
W = 2000lb

3. It is given that the earth weighs 1.5 times as much as water. Therefore:
E = 1.5 * W
E = 1.5 * 2000
E = 3000lb

4. It is also given that the cement block weighs 2.4 times as much as water. Therefore:
C = 2.4 * W
C = 2.4 * 2000
C = 4800lb

Hence, the weight of the cement block is 4800lb.
