Find Volume

Finding Volume

By Aimee Norman

Volume

• The number of cubics units inside a 3-dimensional object.

• The amount of "space" inside an object​

• ​Volume is measured in cubic units

Multiple Choice

Which 3D shape has the greatest volume?

(all the little boxes are the same size)

Multiple Choice

What is the definition of volume?

• The amount of surface area a shape has

• The distance around a shape

• The amount of space an object takes up

• The amount of angles a shape has

Steps for finding Volume of a Prism

• Find the area of the base.

• Multiply the area of the base and the height of the prism.

Rectangular PRISMS

• V = Bh

  • B is the AREA of the BASE

  • Can also be (l x w x h)​

• V= (2 x 5) 4

• V= (10) 4

• V= 40 in cube​

Multiple Choice

What does the "B" in the volume formula V = B x h stand for?

• Bottom of the object

• Box

• Between

• Area of the base

Multiple Choice

Joy wants to create a box with a volume of 8 cubic units. Which dimensions would work?

• length: 8 units
  width: 8 units
  height: 8 units
• length: 2 units
  width 4 units
  height: 3 units
• length: 4 units
  width: 2 units
  height: 2 units
• length: 2 units
  width: 4 units
  height: 1 unit

Triangular PRISMS

• V = Bh

  • B is the AREA of the BASE

  • Triangle Area = bh/2

  • Can also be(bh/2)h

• V = ({5 x 3}/2) x 10

• V = (15/2) x 10​

• V= 7.5 x 10

• V = 75 cm cube​

Multiple Choice

What is the volume of the cylinder?

Use 3.14 for π

Round to the nearest tenth if necessary.

• 376.8 km³

• 300 km³

• 942 km³

• 120 km³

• 188.5 km³
