Question

volume of the cubiod 360 cubic cm and height is 3 cm,breadth is 4 cm.find its length .​

Answer 1

Answer:

30 cm

Step-by-step explanation:

given that,

in a cuboid ,

volume = 360 cm³

height = 3 cm

breadth = 4 cm

we know that,

volume of cuboid = length × breadth × height = 360 cm³

putting the values

length × 4 × 3 = 360

length × 12 = 360

length = 360/12

length = 30 cm

so,

length of the cuboid = 30 cm

____________________

Extra information

total surface area of cuboid  

= 2(lb + bh + lh)

where,

l = length

b = breadth

h = height

lateral surface area of cuboid

2h( l + b)

Volume of cuboid = length × breadth × height.

Answer 2

Answer:

30 cm

Step-by-step explanation:

$Given \ volume \ of \ cuboid \ is \ 360 \ cm^3 \, height =3cm \ and \ breadth=4 \ cm\\\\we \ have \ to \ find \ length\\\\we \ know \ that\\\\ volume \ of \ cuboid =length\times \times breadth \times height\\\\Let \ length \ be \ a \ cm\\\\putting \ values \ here\\\\360 \ cm^3=3 \ cm \times4\times cm \ a\\\\a=\dfrac{360}{12}cm\\\\a=30 \ cm\\\\Thus \ we \ get \ length=30 \ cm$

Important thing that you should have known.

$Diagonal \ of \ cuboid=\sqrt{l^2+b^2+h^2}\\\\\\where \ l, \ b \ and \ h \ are \ length, \ breadth \ and \ height \ of \ cuboid \ respectively.$
