Question

find the lateral surface area and total surface area of the cuboid which length 8cm, breadth 6cm, height 5cm

Answer 1

lateral surface area = 2(l+b) h
so, 2(14)5
=10*14
= 140 cm^2< answer
Total surface area= 2(lb+bh+hl)
= 2(48+30+40)
=2*118
=236cm^2 < answer

Answer 2

HEYA!

QUERY

Find the lateral surface area and total surface area of the cuboid which length 8cm, breadth 6cm, height 5cm

SOLUTION

WE KNOW THAT LATERAL SURFACE AREA(LSA) OF A CUBOID IS 2(L+B)*H AND TOTAL SURFACE AREA (TSA)OF A CUBOID IS 2(LB+BH+LH) SO USE THIS FORMULAS TO GET THE ANSWER

LENGTH= 8CM

BREADTH= 6CM

HEIGHT= 5CM

LSA OF THE CUBOID = 2(L+B)*H

= 2*(8+6)*5

= 2*14*5

=140 CM²

TSA OF THE CUBOID= 2(LB+BH+HL)

= 2*(8*6+6*5+5*8)

= 2* (48+30+40)

= 2*118

= 236CM²

HOPE THIS HELPS
