Question

A box of dimensions 2.5mx2mx1m is to be made. Determine the area of the sheet require when the box is open at the top

Answer 1

Answer:

9m²

Step-by-step explanation:

Length of the box = 2.5m

Breadth of the box = 2m

Height of the box = 1m

L.S.A of the box + lb = Required box

                                  = 2h( l + b ) + lb

                                  = 2 ( 1 ) [ ( 2.5 ) + ( 2 ) ]

                                  = 5 + 4

                                  = 9m²
