Inverse Operations:

Inverse operations are pairs of mathematical operations that "undo" each other. They are used to solve equations by reversing the original operation. The most common pairs of inverse operations are addition and subtraction, multiplication and division, and exponentiation and logarithm. For example, if you have the equation 4 + 2 = x, you can use inverse operations to find the value of x by subtracting 2 from both sides of the equation.

Ratios:

A ratio is a comparison of two or more quantities. It expresses the relationship between the quantities in terms of their magnitude. Ratios can be written in the form of a fraction, using a colon, or as a decimal. For example, if you have a bag with 5 red marbles and 3 blue marbles, the ratio of red to blue marbles would be 5:3, or 5/3.

Proportions:

A proportion is a statement that two ratios or fractions are equivalent. It shows that the relative sizes of the quantities are the same. To solve a proportion, you can use cross-multiplication. For example, if you have the proportion 2/3 = x/9, you can cross-multiply by multiplying 2 and 9, and then divide by 3 to find the value of x.

Formulas for finding the area of 3D shapes:

The formulas for finding the volume of various 3D shapes are as follows:

Cone: Volume = (1/3) * base area * height
Rectangular Prism: Volume = length * width * height
Triangular Prism: Volume = (1/2) * base area * height
Cylinder: Volume = base area * height
Pyramid: Volume = (1/3) * base area * height
Square Pyramid: Volume = (1/3) * base area * height

It's important to note that the formula you provided, Volume = (1/3) * base area * height, is specifically for finding the volume of shapes with a triangular base. For other shapes, the formulas may vary. Make sure to use the appropriate formula for each specific shape.
