Answer:
200 in squared.
Step-by-step explanation:
The top face has a height of 10, it also has a side length of 10. 5 plus 5 equals 10. These faces are squares, so the sides are equal. In this case, they 10 by 10. To find the of the face you do 10 times 10 times 2 because there are 2 figures, or you can find the area of one (100) and the area of the other (100) and add the areas up to get the area of the face. Hope this helps!
Answer:
86ft²
Step-by-step explanation:
3x2/2=3
3x2/6=3
10x2.5=25
10x2.5=25
3x10=30
30+25+25+3+3=86
The answer is 16. To solve this problem, it will look like this:
5 n + n = 24
So, 6(4) = 24. n=4
With this equation, you can see that 4 kids walk to school and 20 take the bus. Then you need to do 20 - 4 = 16. So 16 more kids take the bus than walk to school.
Another way to look at it...
We know there are 5 times as many bus kids as there are walkers.
walkers - n
bus kids - n+n+n+n+n
6n = 24 (the total number of students), which can translate to 6 x n = 24. We know that 6x4=24, so n=4. The number of kids that walk is 4. The number of kids on the bus is 20. So subtract the bus kids from the walking kids, and that leaves us the answer. 16 more students ride the bus than those who walk. I hope that helped.
