Question

Calculate the total surface area of a rectangular box 10cm long, 8cm wide and 6cm tall.​

Answer 1

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
