In geometry, understanding the properties of three-dimensional shapes is essential. A square prism, also known as a rectangular prism with square bases, has specific formulas to calculate its surface area and volume. In this topic, we will learn the formulas for the surface area and volume of a square prism.

List of Math Formulas for Square Prism

To measure the properties of a square prism, we need to know its surface area and volume. Let’s learn the formulas to calculate these properties.

Formula for Volume of a Square Prism

The volume of a square prism is determined by multiplying the area of the base by the height of the prism. It is calculated using the formula: \([ \text{Volume} = \text{Base Area} \times \text{Height} = s^2 \times h ] \)where s  is the side length of the square base, and h is the height of the prism.

Formula for Surface Area of a Square Prism

The surface area of a square prism is the sum of the areas of all its faces. It is calculated using the formula: \([ \text{Surface Area} = 2s^2 + 4sh ] \) where  s is the side length of the square base, and  h  is the height of the prism.

Common Mistakes and How to Avoid Them While Using Square Prism Formulas

Students make errors when calculating the surface area and volume of a square prism. Here are some mistakes and ways to avoid them to master these concepts.

Problem 1

Find the volume of a square prism with a base side length of 4 cm and a height of 10 cm.

Okay, lets begin

The volume is 160 cm³

Explanation

To find the volume, use the formula:\( [ \text{Volume} = s^2 \times h = 4^2 \times 10 = 16 \times 10 = 160 \, \text{cm}^3 ]\)

Well explained 👍

Problem 2

Calculate the surface area of a square prism with a base side length of 3 m and a height of 5 m.

Okay, lets begin

The surface area is 78 m²

Explanation

To find the surface area, use the formula: \([ \text{Surface Area} = 2s^2 + 4sh = 2(3^2) + 4(3)(5) = 18 + 60 = 78 \, \text{m}^2 ]\)

Well explained 👍

Problem 3

Find the volume of a square prism with a base side length of 6 inches and a height of 15 inches.

Okay, lets begin

The volume is 540 in³

Explanation

To find the volume, use the formula: \([ \text{Volume} = s^2 \times h = 6^2 \times 15 = 36 \times 15 = 540 \, \text{in}^3 ]\)
