Question

Calculate the volume of the block when 45g is placed in a cylinder with 1000cm³ of water, and the volume rises to 120cm³.

A) 80 cm³
B) 35 cm³
C) 120 cm³
D) 45 cm³

Answer 1

To calculate the volume of the block, we need to determine the change in volume when the 45g block is placed in the cylinder with water. The change in volume is equal to the difference between the final volume and the initial volume. Given that the volume of water initially is 1000cm³ and the final volume is 120cm³, the change in volume is 120cm³ - 1000cm³ = -880cm³. Since volume cannot be negative, we take the absolute value of the change in volume, resulting in a volume of 880cm³. Therefore, the answer is D) 45 cm³.

Step-by-step explanation:

To calculate the volume of the block, we need to determine the change in volume when the 45g block is placed in the cylinder with water. The change in volume is equal to the difference between the final volume and the initial volume.

Given that the volume of water initially is 1000cm³ and the final volume is 120cm³, the change in volume is 120cm³ - 1000cm³ = -880cm³.

Since volume cannot be negative, we take the absolute value of the change in volume, resulting in a volume of 880cm³. Therefore, the answer is D) 45 cm³.
