Question

please Answer the Question.... :-)

Answer 1

Length f the box = 16 cm

Breadth of box = 12 cm

Height of box = 9 cm

TSA of the box = 2 ( lb + bh + lh )

= 2 ( 16*12+12*9+16*9 )

= 6210 cm ^ 3

Answer 2

The length, breadth and height of box respectively are 16, 12, 9 cm.

Also we know that the total surface area(sum of area of all surfaces) of a cuboid = $\textbf{2(lb+bh+hl)}$

= 2[(16×12)+(12×9)+(9×16)]
= 2 (192+108+144)
= 2 (444)
= 888cm².
