<u>Given</u><u>:</u>
- Breadth, b or width = 6 inches
<u>To</u><u> </u><u>find</u><u> </u><u>out</u><u> </u><u>:</u>
Find the surface area of box ( cuboid ) ?
<u>Formula used </u><u>:</u>
Surface area of cuboid = 2 ( lb + bh + hl )
<u>Solution</u><u>:</u>
We know that,
Surface area of cuboid = 2 ( lb + bh + hl )
★Substituting the values in the above formula,we get
Surface area = 2 ( 5 × 6 + 6 × 8 + 8 × 5 )
= 2 ( 30 + 48 + 40 )
= 2 ( 78 + 40 )
= 2 × 118
= 236 inches³
