The area of the carboard is 2(lb + bh + hl) = 2(40*35 + 35*15 + 15*40) = 2(1400 + 525 + 600) = 5050 cm square

l=0.4m or 40cm
b=35cm
h=15
V=l*b*h
40*35*15
21000cm^3
b=35cm

Area of rectangular cardboard =1400sq.cm
Length = 0.4m
Breadth = 35cm
Height = 15cm
1m = 100cm
0.4m = 0.4×100 = 40
volume of = l×b×h
= 40×35×15
= 21000
