Question

1 m
4) Y = 2,5 m, b = 2 m, h = 4 m
9. A cuboid has the dimensions as shown in the
following diagram. Find its :
(i) volume
(ii) total surface area
(iii) area of four walls
1 m
2 m​

Answer 1

Answer:

Let length of given cuboid be l

Let breadth of the given cuboid be b

Let height of the given cuboid be h

Therefore:

volume of the cuboid = lbh

=2.5*2*4

=20 m^3

TSA = 2(lb+bh+hl)

= 2(5+8+10)

=2(23)

=46 m^2

Area of four walls= CSA of the cuboid=2(l+b)h

=2(2.5+2)4

=2(4.5)4

=36 m^2
