Question

Explain how you can tell when a formula represents a length an area or a volume

Answer 1

To determine if a formula represents a length, area, or volume, consider the units used in the formula.

Step-by-step explanation:

When determining if a formula represents a length, area, or volume, you need to consider the units used in the formula. Length is typically measured in units such as meters or feet. Area is measured in square units, such as square meters or square feet. Volume is measured in cubic units, such as cubic meters or cubic feet.

For example, suppose you have a formula that involves only one variable and it includes units such as meters. This formula would most likely represent a length. If the formula involves two variables and includes units like square meters, then it represents an area. And if the formula involves three variables and includes units like cubic meters, then it represents a volume.

It's important to pay attention to the units to determine whether a formula represents a length, area, or volume.

Answer 2

You can tell when a formula represents each of these by the number of dimensions that are multiplied in the calculation.

Ex:

d = 2r (this would only involve multiplying by one dimension, therefore it is a length)

A = bh (this involves multiplying 2 dimensions, giving a measurement of area)

V = lwh (this involves multiplying 3 dimensions, giving a measurement of volume)
