Question

a board of 5cm 4mm thickness is nailed into a board of 1cm 3mm thickness. how thick is the board now?​

Answer 1

Dear Student,

◆ Answer -

Total thickness of the board = 6 cm 7 mm

● Explanation -

# Given -

Thickness of 1st board = t1 = 1 cm 3 mm = 1.3 cm

Thickness of 2nd board = t2 = 5 cm 4 mm = 5.4 cm

# Solution -

Thickness of the composite board after nailing is -

Total thickness of the board = thickness of 1st board + thickness of 2nd board

Total thickness of the board = t1 + t2

Total thickness of the board = 1.3 + 5.4

Total thickness of the board = 6.7 cm

Total thickness of the board = 6 cm 7 mm

Hence, the board is 6 cm 7 mm thick now.

Thanks dear. Hope this helps you..
