Question

Find area of a cuboid whose base area is 156sq.cm and volume is 1092cm3

Answer 1

326 ( l + b ) sq. cm

Area of base area of cuboid (rectangle) = 156 sq.cm

length * breath = 156 ---(1)

Volume of Cuboid = 1092 cm3

length * breath * height = 1092

               from (1)

156 * h = 1092

h = 1092/156

h = 7 cm

Area of cuboid = 2( l*b + b*h + h*l )

  2 ( 156 + b * 7 + l * 7 )

 312 + 14b + 14l

  312 + 14 ( l+b )

   326 ( l + b ) sq. cm
