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)
=
= 2 (11×6 + 11×5 + 6×5)
= 2 (66 + 55 + 30)
= 2 × 151
= <u>3</u><u>0</u><u>2</u><u> </u><u>in²</u>
So, the surface area is 302 in²
