Answer:
X=12
Step-by-step explanation:
I did this in my head but if you need the explaination tell me in the comments.
First is 42 and the second is 4.5
All you have to do is make and simplify a fraction. In this case, there are 6 friends going into 4 pears, so the fraction is 6/4. Then we can simplify that because they are both divisible by 2. So if we divide both by 2, our fraction becomes 3/2. Then we make that into a mixed number, with 3 going into 2 once with 1 left over. That means the answer is 1 1/2.
Answer: 88 square inches
If we want to wrap the box, we need to work out its surface area - the area that will need to be covered by the giftwrap.
This box is a cuboid, so there will be six faces, with only three different areas (each face has an identical pair).
Let's say the height is 2 in, the length is 6 in and the depth 4 in.
height = 2
length = 6
depth = 4
Let's find the area of the faces that measure height x length:
2 x 6 = 12 square in
Now let's do the same thing for height x depth:
2 x 4 = 8 square in
And finally for length x depth:
6 x 4 = 24
There are two of each of these faces, so let's multiply each result by two.
12 x 2 = 24
8 x 2 = 16
24 x 2 = 48
Finally, all that's left to do is add these numbers together to find the total surface area of the cuboid.
24 + 16 + 48 =
88 square inches
