Answer:
1070cm2
Step-by-step explanation:
the cereal box represents a cuboid and it is closed hence a closed cuboid.
SA- Surface area
L- Length = 15
W- Width =4
H- Height =25
In a closed cuboid, there are going to be 6 faces( 3 pairs).
To find SA, we have to take the area of all faces and sum them up.
You can do this by carrying out the area of all faces and summing them up or you can use the formula:
SA of a closed cuboid=2(L x W) + 2(W x H) + 2(L x H)
= 2(15 x 4) + 2(4 x 25) + 2(15 x 25)
= 2(60) + 2(100) + 2(375)
=120 + 200 + 750
=<u>1070cm2</u>
The answer is 93. its very simple to round well mosly for me cause im smart
First find the area of the whole square. Even the part that isn't part of the area. Then find the area of the spots that aren't part of the shape. Then subtract that area from the area of the whole thing.
15×18=270
(9x12)+(4×5)=128
270-128=142
Area= 142ft^2
The tree will keep growing each year 3 feet.
The answer is seven because if you divide 49 by 7 it equals 7.
