The surface area of the rectangular prism as shown below is 348 meters square.
Surface area of a rectangular prism
surface area = 2(lw + lh + hw)
where
- l = length
- w = width
- h = height
Therefore,
length = 15 m
width = 6 m
height = 4 m
surface area = 2((15 × 6) + (15 × 4) + (4 × 6))
surface area = 2(90 + 60 + 24)
surface area = 2(174)
surface area = 348 m²
