Question

In the discovery activity, how do we use the base area and the height to find volume?

a) Volume = Base Area x Height
b) Volume = Base Area + Height
c) Volume = Base Area / Height
d) Volume = Base Area - Height

Answer 1

To find the volume of a three-dimensional object, you use the formula Volume = Base Area x Height, which is option (a) in the given choices.

Step-by-step explanation:

In the discovery activity, to find the volume of a three-dimensional object like a cylinder, you multiply the base area by the height. Therefore, the correct formula for volume is Volume = Base Area x Height, which corresponds to option (a). Let's break this down with an example: If you have a cylinder with a base area of 10 square units and a height of 5 units, you would calculate the volume by doing the following:

• Identify the base area (A) of the cylinder, which is given as 10 square units.
• Identify the height (h) of the cylinder, which is given as 5 units.
• Multiply the base area by the height to find the volume (V): V = A x h = 10 x 5 = 50 cubic units.

Thus, the volume of the cylinder would be 50 cubic units.
