Answer:

B. 32 square inches

Step-by-step explanation:

Each of the two triangular faces has an area of ...

A = (1/2)bh = (1//2)(6 in)(4 in) = 12 in²

The lateral surface area is the product of the prism height (0.5 in) and the perimeter of the base.

LA = (0.5 in)(5 in +5 in + 6 in) = 8 in²

So, the total area is the area of the two base and the lateral area:

SA = 2A +LA

SA = 2(12 in²) +8 in² = 32 in²

The surface area of the prism is 32 square inches.

Answer:

Step-by-step explanation:

d = 1150 km = 1150 km / 1.61 miles = 714.29 miles

r = 55 mph

d / r = time

714.29 / 55 = 12.99 hours.

The closest time to that is 13 hours.
