Just divide everything by 3, or multiply by a 1/3, so divide all the points and that should give you the answer of all the points.
Answer:
81/5 or 16 1/5.
Step-by-step explanation:
First convert the mixed number to an improper fraction:
3 6/7
= (3*7 + 6) / 7
= 27/7.
So we have
27/7 / 5/21
Invert the second fraction and multiply:
= 27/7 * 21/5
= (27*21) / (7*5)
= (27*3) / 5 ( as 21/7 = 3)
= 81/5
= 16 1/5.

Answer:
Ok so I used an app called Cymath it helps with checking your work and it goes down step by step and I use it for these kind of problems....the last step (3) is your answer.
Step-by-step explanation:
I hope I helped! :)
Remember are for rectangles or squares is l*h*w
Area for triangle or a trapezoid is l*w*h/2
a. 5 * 7 * 14: 5 * 7 = 35 35 * 14 = 490 So, the volume for letter a is 490 cm3
I'm sorry but what I could get so far is this because I don't really no how to do the triangular prism but this might help you <span>https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=formula+for+triangular+...</span>
