i need the steps please.

Answer:A
Step-by-step explanation:
Length=L=15cm
Width=w=8cm
Height=h=2cm
Surface area=(2xwxL)+(2xLxh)+(2xhxw)
Surface area=(2x8x15)+(2x15x2)+(2x2x8)
Surface area=240+60+32
Surface area=332 cm^2
Answer:
a. 332 cm²
Step-by-step explanation:
Surface area is the sum of areas of 6 rectangular faces of the box
Opposite faces have equal areas
SA = 2[(15×8) + (15×2) + (8×2)]
= 2[120 + 30+ 16]
= 2(166)
= 332 cm²
