2) The two solid blocks represented in the diagram are made of the same material and are under the same temperature and pressure
scoundrel [369]

Answer:

54 g

Explanation:

We'll begin by calculating the density of X. This can be obtained as follow:

Mass of X = 54 g

Length (L) = 9 cm

Breadth (B) = 2 cm

Height (H) = 1 cm

Volume of X = L × B × H

Volume of X = 9 × 2 × 1

Volume of X = 18 cm³

Density of X =?

Density = mass /volume

Density of X = 54/18

Density of X = 3 g/cm³

Finally, we shall determine the mass of Y as follow:

Length (L) = 3 cm

Breadth (B) = 3 cm

Height (H) = 2 cm

Volume of Y = L × B × H

Volume of Y = 3 × 3 × 2

Volume of Y = 18 cm³

Density of Y = Density of X (since they are made of the same material)

Density of X = 3 g/cm³

Density of Y = Density of X = 3 g/cm³

Mass of Y =.?

Density = mass /volume

3 = mass of Y /18

Cross multiply

Mass of Y = 3 × 18

Mass of Y = 54 g
