Given:
Consider the dimensions of the cuboid are 5 by 4 by 6.
To find:
The total surface of the cuboid.
Solution:
The total surface area of a cuboid is:
[tex]Area=2(lb+bh+hl)[/tex]
Where, l is length, w is width and h is the height.
Substituting l=5, b=4 and h=6, we get
[tex]Area=2(5\times 4+4\times 6+6\times 5)[/tex]
[tex]Area=2(20+24+30)[/tex]
[tex]Area=2(74)[/tex]
[tex]Area=148[/tex]
Therefore, the total surface area of the cuboid is 148 sq. units.
