Question

find the surface area of a cuboid whose length=2m, breadth=4m, height=5m​

Answer 1

Answer:

$total \: surface \: area \: of \: cuboid = 2(lb + bh + hl)$

Step-by-step explanation:

l=2m

b=4m

h=5m

• A=2(2×4+4×5+5×2)
• A=2(8+20+10)
• A=2(38)
• A=76
• $76m {}^{2}$

Answer 2

the surface area of cuboid =2(lb +bh+hl) =2*{(2m*4m)+(4m*5m)+(5m*2m)}

=2*{8m2+20m2+10m2}

=2*{38m2}

=76m2

hence the surface area of cuboid is=76m2
