A rectangular box 40cm*20cm*20cm is to be made up of tin. what is the area if tin sheet required if the box is without a lid.
Answers
Answer:
Step-by-step explanation:
Length of box(l)=40cm
Breadth of box(b)=20 cm
Height of box(h)=20cm
Required area of box=Total surface
area of box-
area of one face
=6(lb+bh+hl)-(lb+bh+hl)
=5(lb+bh+hl)
=5(40*20+20*20+20*40)
=5(800+400+800)
=5(2000)
=10,000 sq. cm
So,area of tin required=10,000sq. cm
Answer:
Step-by-step explanation:
L=40
B=20
H=20
CSA=2(l+b)h
=2(40+20)*20
2*60*20
2400cm sq
Area of lid
L*b=40*20=800
Area of the tin required=csa+ area of lid is equal to 240 + 800 =3200cm sq
