The surface area of the composite shape is 1560 square inches
<u>Step-by-step explanation:</u>
The surface area of the top cardboard is,
SA = 5 x area of each side
Because one side is attached with another cardboard box . So while finding the area only 5 sides are calculated.
SA = 5 ( 10 x 10)
= 500 square inches
The surface area of the rectangular prism cardboard,
Given that,
l = 20 in
w =15 in
h = 8 in
A = 2(lw + wh + hl) - 100
We are subtracting 100 because it is the area of one side of the square cardboard box on top of the rectangular prism box .
A = 2(300 + 120 + 160) - 100
= 2(580) - 100
= 1160-100
= 1060 square inches
Total surface area = SA + A
= 500 + 1060
= 1560 square inches
Step-by-step explanation:
a power supply, a load suited to the power supply, and wiring as a conductor
60%
If you take the 30% and divide from the 50% you get .6 multiply that by a 100 you get 60.
30/50=.60
.60x100=60
60%
Answer:
Step-by-step explanation:
We'll need the actual prices of one of the objects to figure it out...
but I've worked it out here in relation to each object....
Marker = 1/3 x cost of the pen
Marker = 1/3 x 1/3 x cost of book = 1/9 x cost of the book
Marker = 1/3 x 1/3 x 1/3 x cost of game = 1/27 x cost of the game
This probably isn't what you're looking for, but maybe it'll help?
