Unit 11 Volume and Surface Area Test Overview
The Unit 11 Volume and Surface Area Test assesses students’ understanding of the concepts and formulas related to the volume and surface area of 3D shapes.
The test covers a range of shapes, including cubes, rectangular prisms, cylinders, cones, and spheres. Students will be required to apply formulas to calculate the volume and surface area of these shapes.
Key Concepts and Formulas, Unit 11 volume and surface area test answers
The following are the key concepts and formulas covered in the test:
- Volume: the amount of space occupied by a 3D shape
- Surface area: the total area of the surfaces of a 3D shape
- Volume of a cube: V = s^3, where s is the length of a side
- Volume of a rectangular prism: V = lwh, where l is the length, w is the width, and h is the height
- Volume of a cylinder: V = πr^2h, where r is the radius of the base and h is the height
- Volume of a cone: V = (1/3)πr^2h, where r is the radius of the base and h is the height
- Volume of a sphere: V = (4/3)πr^3, where r is the radius
- Surface area of a cube: A = 6s^2, where s is the length of a side
- Surface area of a rectangular prism: A = 2(lw + wh + lh), where l is the length, w is the width, and h is the height
- Surface area of a cylinder: A = 2πrh + 2πr^2, where r is the radius of the base and h is the height
- Surface area of a cone: A = πr^2 + πrl, where r is the radius of the base and l is the slant height
- Surface area of a sphere: A = 4πr^2, where r is the radius
