Answer 1

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete; as the sides of the prism are not given.

To solve tis question, I'll make the following assumptions:

$Length (L) = 6 cm$

$Width (W) = 4 cm$

$Height (H)= 2 cm$

The formula given in the question can be translated to:

$SA = 2(W * H + H * L + W * L)$

Using the assumed values, we have:

$SA = 2(4 * 2 + 2 * 6 + 4 * 6)$

$SA = 2(8 + 12 + 24)$

$SA = 2(44)$

$SA = 88cm^2$
