Question

how many square metres of wood is required to make a closed box from dimensions 2.5m*2.om*1.5m​

Answer 1

Answer:

23.5 m²

Step-by-step explanation:

Wood required = Total surface area of box

T.S.A. of cuboid = 2 (lb + bh + hl)

Given, length = 2.5 m, breadth = 2 m, height = 1.5 m.

=> T.S.A. = 2 (2.5×2 + 2×1.5 + 2.5×1.5) m²

=> T.S.A. = 2 (5 + 3 + 3.75) m²

=> T.S.A. = 2 (11.75) m² = 23.5 m²

Answer 2

23.5 m² is the right answer
