B. 180cm3
You have to find length, width, and height of both objects.
For the first one multiply:
3 x 8 x 5 = 120
Then multiply:
2 x 5 x 6 = 60
Add them together:
120 + 60 = 180cm3
6.25 because 2.5+2.5= 5 and then half of 2.5 is 1.25 so 6.25
Notice the picture below
the lateral area, or just the area of the sides, well, the sides are really just 4 triangles, so just get the area of each, and sum them up, that's the lateral area
Fee for distance = total fee - initial fee = 12.70-2.20 = $10.50
Now, for 1 mile = $1.50
for x miles = 10.50/1.50 = 7
So, tom travel 7 miles.
