Triangular Prism- SA= 1/2bh
= 1/2 × 7 × 11
= 38 1/2 × 4 = 154
7 × 7 = 49
= 154 + 49
= 204in³
Rectangular Prism- SA= 2lw + 2lh + 2wh
= 2 × 11 × 7 + 2 × 11 × 7 + 2 × 7 × 7
= 154 + 154 + 98
= 406in³
Therefore, the rectangular prism has the larger surface area.

Step-by-step explanation:
60 miles in 1 hour.
Distance is equivalent to the rate multiplied by time.
d = 60h

using d = 60h
d = 60 miles * 4 hours
d = 240 miles.
