Question

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

Answer 1

Answer:

6cm 7mm

Step-by-step explanation:

Thickness of attached board= 5cm 4mm

Thickness of board which is already attached= 1cm 3mm

Therefore, thickness of board = 5cm 4mm + 1cm 3mm= 6cm 7mm

Answer 2

Answer - Total thickness of the board = 6 cm 7 mm cm

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

# 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 mm thick now .

Thanks dear. Hope this helps vu ..
