Which one is correct?

The volume of the prism is other; 5.04 m^3

Step-by-step explanation:

Here, we want to get the volume of the prism

What we have to do here is to calculate the area of the trapezoid base and multiply by the height of the prism

The area of the base is;

A = 1/2(a + b) h

a and b are the parallel sides of the trapezoid which is 80 cm and 2 m

h is the height of the trapezoid which is 1.2 m

80 cm is same as 80/100 = 0.8 m (100 cm = 1 m)

A = 1/2( 0.8 + 2)1.2

A = 1/2 * 2.8 * 1.2 = 1.68 m^2

So we proceed to multiply this with the height of the prism which is 3 m

This will be ;

1.68 m^2 * 3 m = 5.04 m^3

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
