Rectangular Prism Volume and Surface Area Worksheet with Decimals – Grade 6

To find the volume of a rectangular prism with decimal dimensions, you follow the same standard formula but pay close attention to decimal multiplication.

1. First, identify the length, width, and height of the prism, which will be decimal numbers.
2. Next, use the formula Volume = length × width × height.
3. Multiply the three decimal values together carefully.
4. The final answer will be in cubic units, reflecting the three dimensions multiplied.

This worksheet provides ample practice for multiplying decimals in a geometry context.

The main difference between area and surface area is that area is for 2D shapes while surface area is for 3D shapes.

• Area: This measures the space inside a flat, 2D shape like a square or a rectangle. It is calculated with two dimensions (e.g., length × width).
• Surface Area: This is the total area of all the outside surfaces (faces) of a 3D object like a rectangular prism. You calculate the area of each face and add them together.

This worksheet is designed to build several important mathematical skills for Grade 6 students.

• Decimal Multiplication: Solving problems with decimal dimensions strengthens calculation accuracy.
• Formula Application: It provides practice in correctly applying the formulas for volume and surface area.
• Problem Solving: The included word problems encourage students to apply concepts to real-world problems.
• Geometry Visualization: Working with diagrams helps students understand the properties of 3D shapes.
