What is the surface area of side B?

What is the surface area of side B?

5mm__x 5mm__

25mm^{2}

What is the total surface area?

What is the total surface area?

5mm__x 5mm__

25mm^{2}

5mm__x 10mm__

50mm^{2}

50mm^{2}__x 4__

200mm^{2}

25mm^{2}__x 2__

50mm^{2}

200mm^{2}__+ 50mm ^{2}__

250mm

^{2}

You would find the surface area for every side and add them together. Since there are two sides that equal 25mm^{2} and 4 sides that equal 50mm^{2}, this leads to our third and fourth equations above.

These added together equal our answer.

What is the volume of the block?

What is the volume of the block?

5mm x 5mm x 10mm=

250mm^{3}

Convert:

50*F to *C

50*C to *F

(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

B. Arm

C. Coarse Focus

D. Fine Focus

E. Base

F. Light Source

G. Mechanical Stage
