When you put a rock into a container of water, it raises the water level 3 cm. If the container is a rectangular prism whose base measures 15 cm by 15 cm, what is the volume of the rock

Answer 1

Since the volume of the rock will be equal to the change in the volume of water in the prism, and since the volume of any rectangular prism is calculated via the formula V = l x w x h, we calculate as follows: the length and width of the prism are fixed at 15 cm and 15 cm and the height of the water undergoes a change of 3 cm, so we multiply 15 x 15 x 3 to determine the volume of the rock placed in the water to be 675 cubic cm.
