What is the formula for the surface area of a rectangular prism? (2 points) Responses S.A. = bh + (S1+S2+S3)⋅l S.A. = bh + (S1+S2+S3)⋅l S.A. = 2(w ⋅ l)+2(w ⋅ h)+2(l ⋅ h) S.A. = 2(w ⋅ l)+2(w ⋅ h)+2(l ⋅ h) S.A. = l ⋅ w ⋅ h S.A. = l ⋅ w ⋅ h S. A. = 13⋅(l⋅w)⋅H

1 answer

The correct formula for the surface area (S.A.) of a rectangular prism is:

\[ \text{S.A.} = 2(l \cdot w) + 2(w \cdot h) + 2(l \cdot h) \]

or, equivalently,

\[ \text{S.A.} = 2(lw + lh + wh) \]

Where:

  • \( l \) = length
  • \( w \) = width
  • \( h \) = height

So the response that correctly represents this is:

S.A. = 2(w ⋅ l) + 2(w ⋅ h) + 2(l ⋅ h).
