A concrete slab with a volume of 2.5 m3 has a mass of 4.75 tons

A concrete slab with a volume of 2.5 m3 has a mass of 4.75 tons, which is the abem of a slab made of the same concrete if its mass is 6.65 tons.

Since we are given the volume and mass of one concrete slab and the mass of another concrete slab, we can use the usual proportion to find the volume of the second slab. Let’s designate the unknown volume of the second slab by X. Then we can make a proportion of the form:

2.5: 4.75 = X: 6.65 – from here we find X, that is, our volume:

X = (6.65 * 2.5) / 4.75 = 16.625 / 4.75 = 3.5 m3.

Answer: 3.5 m3.
