100

What is the formula for finding the volume?

V = l x w x h

200

What is the unit measure for volume?

Cubic units

300

What is the volume of a box that is 4m long, 2m wide, and 3m high?

V = 4 x 2 x 3 

V = 24m³

400

What is the formula for surface area?

SA = 2lw + 2lh + 2wh

500

Find surface area for a prism that has dimensions 6cm by 5cm by 2cm. 

SA = 2(6)(5) + 2(6)(2) + 2(5)(2)

SA = 60 + 24 + 20

SA = 104cm²

Cylinders

100

What is the formula for volume?

V = (pi)r²h

200

What is the volume of a can with a height of 10cm and a radius of 3cm.

V = 3.14(3)²(10)

V = 282.6cm³

300

What is the formula for surface area?

SA = 2(pi)r(h+r)

400

Find surface area for a cylinder that has a height of 5m and a radius of 2m.

SA = 2(3.14)(2)(5+2)

SA = 87.92m²

500

What happens to the volume if the height of the cylinder is doubled?

The volume doubles

Rectangles

100

What is the formula for area?

A = l x w

200

What is the formula for perimeter?

P = 2(l+w)

300

True/False: All squares are rectangles.

True

400

Find the width when a rectangle has a perimeter of 30, and a length of 10.

30 = 2(10+w)

15 = 10+w

5 = w

500

What happens to the area of a rectangle when the dimensions are tripled?

Area gets 9 times larger

Circles

100

Formula for area of a circle.

A = (pi)r²

200

What is the circumference equation?

C = 2(pi)r

300

Find the area when the radius is 7cm.

A = 3.14(7)²

A = 153.86cm²

400

If the radius triples, what happens to the circumference?

It also triples

500

If the radius doubles, what happens to the area?

It becomes 4 times larger
