Calculation of the Volume and Surface Area of a Book

To calculate the volume and surface area of a book, we need to know the dimensions of the book. In this case, the given dimensions are as follows:

- Length: 20 cm - Width: 10 cm - Height: 3 cm

Calculation of Volume

The volume of a parallelepiped (which is a type of prism) can be calculated by multiplying the length, width, and height of the shape. In this case, the volume of the book can be calculated as follows:

Volume = Length x Width x Height

Substituting the given values:

Volume = 20 cm x 10 cm x 3 cm

Calculating the product:

Volume = 600 cm³

Therefore, the volume of the book is 600 cubic centimeters.

Calculation of Surface Area

The surface area of a parallelepiped can be calculated by adding the areas of all its faces. In this case, the book has six faces: two rectangular faces on the top and bottom, and four rectangular faces on the sides.

The formula to calculate the surface area of a parallelepiped is as follows:

Surface Area = 2lw + 2lh + 2wh

Substituting the given values:

Surface Area = 2(20 cm x 10 cm) + 2(20 cm x 3 cm) + 2(10 cm x 3 cm)

Calculating the product:

Surface Area = 400 cm² + 120 cm² + 60 cm²

Surface Area = 580 cm²

Therefore, the surface area of the book is 580 square centimeters.

Conclusion

To summarize, the given book has a volume of 600 cubic centimeters and a surface area of 580 square centimeters.
