The surface area of a rectangular prism can be calculated using the formula:
Surface Area = 2lw + 2lh + 2wh
Given:
l = 3 dm
w = 4 dm
h = 5 dm
Plugging in the values:
Surface Area = 2(3)(4) + 2(3)(5) + 2(4)(5)
Surface Area = 24 + 30 + 40
Surface Area = 94 dm²
Therefore, the surface area of the rectangular prism is 94 dm².
