Answers
Step-by-step explanation:
Answer:
The volume of the cuboid is 60 centimeter cube.
Step-by-step explanation:
Given : The area of three consecutive faces of cuboid are 12cm square, 20cm square and 15cm square.
To find : The volume of the cuboid ?
Solution :
Let the dimensions of the cuboid,
Length = l
Breadth = b
Height = h
We have given,
l\times b=15 \text{ cm}^2l×b=15 cm
2
.....[1]
b\times h=20 \text{ cm}^2b×h=20 cm
2
.......[2]
l\times h=12 \text{ cm}^2l×h=12 cm
2
.......[3]
Volume of the cuboid is V=lbhV=lbh
Multiply [1] , [2] and [3] we get,
lb\times bh\times lh=(lbh)^2lb×bh×lh=(lbh)
2
15\times 20\times 12=(lbh)^215×20×12=(lbh)
2
3600=(lbh)^23600=(lbh)
2
lbh=\sqrt{3600}lbh=
3600
V=60\text{ cm}^3V=60 cm
3
Therefore, The volume of the cuboid is 60 centimeter cube
