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)
= [tex] \boxed{2 (l.w + l.h + w.h)} [/tex]
= 2 (11×6 + 11×5 + 6×5)
= 2 (66 + 55 + 30)
= 2 × 151
= 302 in²
So, the surface area is 302 in²
