Question

Find the surface area

Answer 1

Answer:

The surface area is 302 in²

Step-by-step explanation:

Known :

Long (l) = 11 in

Weight (w) = 6 in

Height (h) = 5 in

Asked :

Surface Area (Sa) = ...?

Answer :

Formula :

= 2(l.w) + 2(l.h) + 2(w.h)

= $\boxed{2 (l.w + l.h + w.h)}$

= 2 (11×6 + 11×5 + 6×5)

= 2 (66 + 55 + 30)

= 2 × 151

= 302 in²

So, the surface area is 302 in²
