2 x 2 x 5 = 20
4 x 2 x 2 = 16
20 + 16 = 36
Ans: 36 cubic feet
Answer:
Option (b).
Step-by-step explanation:
It is given that Adrian built a structure out of 10 congruent cubes.
Volume of each cube = 8 cubic centimetres.
We need to find the total volume of the structure.
Total volume = No. of cubes × Volume of each cube
Therefore, the total volume of the structure is 80 cubic centimetres.
Hence, option (b) is correct.
Answer:

Step-by-step explanation:
Since it takes 10 min to walk a half of mile, it will take 20 min to walk a whole mile.
Since we will be walking one and a half miles, it should take about 30 minutes.
Hope this helps.
The answer to the first one is a
Step-by-step explanation:
7. Since they are similar triangles we have:

So DF is 15
8. They are also similar. So:

So PR is 10
