Question

The length of each edge of a cube is 3 cm. its mass is 216g. how many ml of water will it displace when it is completely submerged in water?

a) 27 ml
b) 54 ml
c) 81 ml
d) 108 ml

Answer 1

The volume of the cube is 27 mL, so it will displace 27 ml of water when completely submerged.

Step-by-step explanation:

To calculate the volume of the cube, we need to find the cube multiplication of its edge length. Since each edge of the cube is 3 cm, the volume would be 3 cm x 3 cm x 3 cm = 27 cm³.

Since 1 mL is equal to 1 cm³, the volume of the cube is also equal to 27 mL.

Therefore, the cube will displace 27 mL of water when it is completely submerged.
