1,000

1/100

1/1,000

1/1,000,000

1/1,000,000,000

5
Q

What is the surface area of side B?

A

What is the surface area of side B?

5mm
x 5mm
25mm2

6
Q

What is the total surface area?

A

What is the total surface area?

5mm
x 5mm
25mm2

5mm
x 10mm
50mm2

50mm2
x 4
200mm2

25mm2
x 2
50mm2

200mm2
+ 50mm2
250mm2

You would find the surface area for every side and add them together. Since there are two sides that equal 25mm2 and 4 sides that equal 50mm2, this leads to our third and fourth equations above.

7
Q

What is the volume of the block?

A

What is the volume of the block?

5mm x 5mm x 10mm=

250mm3

8
Q

Convert:

50*F to *C

50*C to *F

A

(50-32) x 5/9=10*C

50 x 9/5 + 32= 122*F

*C = (*F-32) x 5/9

*F = *C x 9/5 + 32
