The height of nothing is 8cm and it's breadth is 4cm find length
Answers
Step-by-step explanation:
The length of a cuboid = 4cm.
The breadth of a cuboid = 5cm.
The height of a cuboid = 8cm.
To find out,
The L.S.A of cuboid. It means we have to find out the lateral surface area.
Solution:
\huge \: Lateral \: surface \: area(L.S.A) of cuboid \: of \: cuboid \: = 2h(l + b)Lateralsurfacearea(L.S.A)ofcuboidofcuboid=2h(l+b)
Where,
h = height of cuboid
l = length of cuboid
b = breadth of cuboid
Now, substitute the values of length, breadth and height in the formula to find out the lateral surface area of cuboid.
lateral \: surface \: area \: of \: cuboid \: = 2 \times 8(4 + 5)lateralsurfaceareaofcuboid=2×8(4+5)
lateral \: surface \: area \: of \: cuboid \: = 16(9)lateralsurfaceareaofcuboid=16(9)
lateral \: surface \: area \: of \: cuboid \: = 144 {cm}^{2}lateralsurfaceareaofcuboid=144cm

Therefore the lateral surface area of cuboid is 144 square meters.
