Answer:
Surface area is =548
Volume = 840 in³
Step-by-step explanation:
l × w, l × w, w × h, w × h, l × h, l × h
70 + 70 + 84 + 84 + 120 + 120 = 548
l × w × h = 840

Answer: 140%
Step-by-step explanation:
First, you must find out how much you'll be making. To do this, multiply 356 by .4 (to get 142.4). If you're making 40% profit, you must add 142.4 to 356 (or else you'd be losing money!). We now know whoever sold these bike racks made 498.4 dollars. Divide this by 356 and get 1.4 which converts to a 140% markup up price (also meaning the price the racks were sold at is 1.4 times the price bought).
Hope this answers your question! Best of luck.
Answer:
The volume of the pentagonal prism is 1446.25
Step-by-step explanation:
First of all we need to calculate the area of the pentagon
A = area
a = apothem = 8.9
p = perimeter = 13 * 5 = 65
A = (a*p) / 2
A = (8.9 * 65) / 2
A = 578.5 / 2
A = 289.25
To calculate the volume of a pentagonal prism we have to use the following formula:
a = area = 289.25
v = volume
h = height = 5
v = a * h
we replace the values that we know
v =
289.25 * 5
v = 1446.25
The volume of the pentagonal prism is 1446.25
