Surface Area

What is the formula to find the area of any rectangle?

• A=bh

• A=1/2h (b+b)

• A=1/2bh

• A=c/d

What is the formula to find the area of any square?

• A=side x side

• A=bh

• A=bh/2

• A=bh/3

What is the general way to find the area of a net?

• You throw the net in the water

• You find the area of each part of the net, then add all the parts together

• You find the area of each part of the net then divide everything by 2

• You multiply all the numbers together

Total surface area means...

• You find the area of just the bases

• You find the area of every single part

• You only find the area of any triangles

• You find the volume of the shape

What is the difference between lateral surface area and total surface area?

• Nothing, they are the same

• Lateral is when you divide everything by 3

• Lateral is just finding the top and the bottom area only

• Lateral surface area is just the area of the sides and not the bases, while total is everything.

2x+6=10

What is the first step to solve this question?

• Divide by 2 on both sides.

• Subtract 6 from both sides

• Add 10 to both sides

• Add 6 to both sides

Solve for x

2x+6=10

• x=2

• x=8

• x=-1

• x=246

What types of numbers go in the rational set of numbers?

• ONLY whole numbers

• ONLY negative numbers

• All numbers, all fractions and all decimals

• Square roots and Pi

What equation would match the situation below:

Sarah had $600 in her account but wrote a check for $5 each week to go to the movies. How many weeks until she has only $100 in her account?

• 100x-600=5

• 600x+5=100

• 600-5x=100

• 100x-5=600

What IS pi (not what is pi worth, but what can we do to every circle in the world to get Pi)?

• bh

• circumference/

  diameter

• radius squared

• 3.14
