Answer:
41 1/6 is the answer lets do it step by step
Step-by-step explanation:
You are usually taught to multiply the improper fractions and simplify the result.
.. (38/3)*(13/4) = (38/4)*(13/3)
.. = (19/2)*(13/3)
.. = (19*13)/6
.. = 247/6
.. = 41 1/6
You can also multiply the parts.
.. (12 2/3)*(3 1/4) = 12*3 + 12*(1/4) +(2/3)*3 +(2/3)*(1/4)
.. = 36 +3 +2 +1/6
.. = 41 1/6

you have n items and how many ways are there to chose r of them
nCr=

remember than n! means n times all numbers before like
3!=3*2*1, 5!=5*4*3*2*1

A) Net A would be the correct net for the prism.
B) AB = 3in
BC = 5in
CD = 8.6in
C) area of one triangle : 4*3/2 = 6
But there's 2 triangles so 6*2 = 12cm2
Area of the middle square : 8.6*4 = 34.4cm2
Area of bottom square : 8.6*5 = 43cm2
Area of top rectangle : 8.6*3 = 25.8cm2
Finally add all of these areas together and you will get the surface area : 115.2cm
