Answer 2

Calculating the Surface Area of a Rectangular Prism

To find the surface area of a rectangular prism, we can use the formula:

Surface Area (S) = 2lw + 2lh + 2wh

Where: - l = length - w = width - h = height

Given the dimensions of the rectangular prism as: - Length (l) = 4 cm - Width (w) = 7 cm - Height (h) = 13 cm

We can calculate the surface area using the provided formula.

Calculation

Using the given dimensions: - Length (l) = 4 cm - Width (w) = 7 cm - Height (h) = 13 cm

We can substitute these values into the formula:

Surface Area (S) = 2lw + 2lh + 2wh

S = 2(4)(7) + 2(4)(13) + 2(7)(13)

S = 56 + 104 + 182

S = 342 cm²

So, the surface area of the rectangular prism is 342 cm².

This calculation is based on the formula for the surface area of a rectangular prism and the given dimensions of the prism. [[7 #]]
