Surface area of the cuboid

One Side of the cuboid= 4 cm

[tex] \red \bigstar \sf \: \red how \: to \: find : [/tex]

To find the surface area of a cuboid is :

[tex] \sf \: 2(l b + bh + hl)[/tex]

• L=16 cm
• B=4 cm
• H=4 cm

[tex] \sf \implies 2(16 × 4 + 4 × 4+ 16 × 4)[/tex]

[tex] \sf \implies 2(64 + 16 + 64)[/tex]

[tex] \sf2(144) = 288[/tex]

So the surface area of cuboid= 288 cm²
