Answer 2

Answer:

∴ Surface area of a cuboid is $12564$ sq.cm.

Step-by-step explanation:

In context with question asked,

• We have to find the surface area of cuboid.
• It is given that, $L=9$ cm, $B=92$ cm, $H=54$ cm
• The formula for surface area of cuboid is given by,

      Surface area of a cuboid = $2lw+2lh+2hw$

                               = $2\times 9\times92+2\times9\times 54+2 \times 92\times54$

                               = $1656+972+9936$

                               = $12564$ sq.cm.

• ∴ Surface area of a cuboid is $12564$ sq.cm.
