Question

6. A cubical box has each edge 10 cm and another cuboidal box is 12.5cm long 10cm wide and 8cm high Which
box has the greater lateral surface area and by how much​

Answer 1

edge of cubical box=10cm

LSA=6l²

=6*10*10

=600cm²

length of cuboidal box =12.5

breadth=10

height=8

LSA=2(lb+bh+hl)

=2(12.5*10+10*8+8*12.5)

=2*(125+80+100)

=2*305

=610cm²

therefore the LSAof cuboidal box is 10 cm² is greater than cubical box
