Question

1. Find the volume and total surface area of a cuboid when:
(i) Length = 4.5 m, breadth = 3.4 m and height = 2.6 m​

Answer 1

Answer:

l=4.5m

b=3.4m

h=2.6m

volume=l*b*h

  = 4.5*3.4*2.6

  =39.78m

total surface area=2*(lb+bh+lh)

                            =2*(15.3+8.84+11.7)

                            =2*35.84

                              =71.68m

Step-by-step explanation:

Answer 2

Step-by-step explanation:

volume of a cuboid = l*b*h

= 4.5m * 3.4m * 2.6m

=39.78 m^3

Surface area of a cuboid =2(lb+lh+bh)

=2(4.5 *3.4 + 4.5*2.6 + 3.4*2.6)

=2(15.3 + 11.7 + 8.84)

=2(35.84)

=2 * 35.84

=71.68 m^2
