What is the surface area of side B?
What is the surface area of side B?
5mm
x 5mm
25mm2
What is the total surface area?
What is the total surface area?
5mm
x 5mm
25mm2

x 10mm
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.
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=
250mm3
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
What are the following parts and their function(s)?
A. Body Tube
B. Arm
C. Coarse Focus
D. Fine Focus
E. Base
F. Light Source
G. Mechanical Stage
H. Nosepiece

Heterozygous, Homozygous
