Answer:
The answer is
376 cm²
Step-by-step explanation:
Since the rectangular box is a cuboid,
Total surface area of a cuboid is given by
2( lw + wh + lh)
Where
l is the length
w is the width
h is the height
From the question
l = 10 cm
w = 8cm
h = 6cm
Substitute the values into the above formula
That's
Total surface area of the rectangular box is
2 [ (10)(8) + (8)(6) + (10)(6) ]
2 [ 80 + 48 + 60 ]
2( 188)
We have the final answer as
Total surface area = 376 cm²
