Question

an open cardboard box is 20 cm long 12 cm wide and 8 cm deep calculate the total area of cardboard in the box​

Answer 1

Answer:

we know that,

we know that,l =20 cm

we know that,l =20 cmb =12 cm

we know that,l =20 cmb =12 cmh = 8 cm

we know that,l =20 cmb =12 cmh = 8 cmso,

we know that,l =20 cmb =12 cmh = 8 cmso,Area of cuboid = l×b×h

we know that,l =20 cmb =12 cmh = 8 cmso,Area of cuboid = l×b×h = 20×12×8

we know that,l =20 cmb =12 cmh = 8 cmso,Area of cuboid = l×b×h = 20×12×8 = 1920 cm^2
