Question

find the lateral surface area, the total surface area and the volume of the cuboid whose dimensions are: length=80cm ,breadth=40cmand height=25cm​

Answer 1

Answer:

LENGTH(l)=80 cm

BREADTH(b)=40 cm

HEIGHT(h)=25 cm

TSA OF CUBOID = 2(lb+bh+lh)

                            = 2[(80*40)+(40*25)+(25*80)] cm²

                            =2[3200+1000+2000] cm²

                            =2[6200] cm²

                            =12400 cm²

LSA OF CUBOID=2(l+b)h

                           =2(80+40)25 cm²

                           =2(120)25cm²

                           =50(120) cm²

                           =600 cm²

                           

Answer 2

Step-by-step explanation:

LSA= 2(l+b)h

= 2(80+40) 25

= 50(120)

=6,000 cm²

TSA=2(lb+bh+hl)

=2(80×40+40×25+25×80)

=2(3200+1000+2000)

=2(6200)

=12,400 cm²

Volume= lbh

=80(40)(25)

=80×1000

=80,000cm³
