Can u pls me with 6,8, and 10. thx on 8 explain

6) is 18

8) yes bill is right. if you find the volume of both the shapes then you will find that the volume of both is 960cm. so yes both of them have the same volume.

10) 10 tons

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
