Question

find the volume of a cuboid of dimensions 18 cm into 120 mm into 150 mm in cubic metres​

Answer 1

Answer:

Here, The dimensions are in cm and mm. Since we have to find the volume in cm³ (or cu cm), we will convert all the dimensions into cm. To do so,

Keep the dimensions in cm the same as they are.

For the dimensions which are in mm, divide them by 10 to obtain their values in cm.

18 cm = 18 cm

120 mm = 120 ÷ 10 = 12 cm

150 mm = 150 ÷ 10 = 15 cm

Now, to get the volume, we need to multiply all the dimensions.

Thus, Volume of cuboid = 18 cm × 15 cm × 12 cm                                                                                                     = (18 × 12 × 15) cm³                                                                                                  = 3240 cm³

Answer 2

$\huge{\underline{\purple{\rm{Solution:}}}}$

$\small{\underline{\red{\rm{Given:}}}}$

• $\rm{The\: dimensions\:of\: cubiod}$
• $\rm{Length=18cm}$

• $\rm{Breadth=120mm}$

• $\rm{Height=150mm}$

$\small{\underline{\purple{\rm{To\: Find:}}}}$

• $\rm{The\: Volume\:of\: cubiod\:m^3}$
• Before calculating convert the unit here
• As we know that
• 1m=1000mm
• 1m=100cm

$\small{\underline{\purple{\rm{As\:per\:the\: above\: information:}}}}$

• $\rm{Length=18cm=\dfrac{18}{100}=0.18m}$

• $\rm{Breadth=120mm=\dfrac{120}{1000}=0.12m}$

• $\rm{Height=150mm=\dfrac{150}{1000}=0.15m}$

$\rm\green{\implies Volume\:of\: cubiod=l*b*h}$

$\rm{\implies Volume=0.18*0.12*0.15}$

$\rm{\implies Volume=0.00324\:m^3}$

Hence,

$\rm\red{\implies Volume\:of\: cubiod=0.00324\:m^3}$
