Question

a box with lid is made out of 2cm thick wood it's external length,breadth and height are 25cm,18cm and 15cm respectively . find the capacity of the box and volume of the wood used​

Answer 1

Answer:

Capacity = 3234 cubic centimetre (c.c.)

Volume = 6750 cubic centimetre (c.c.)

Step-by-step explanation:

• It's given that,

         The external length = 25 cm

                             breadth = 18 cm

                      and,  height = 15 cm

• Now, because we need to find the volume or capacity of the box, let us find out the internal measurements:

        The internal length = 25-2+2 cm (as there are two sides with the same                    thickness of the wood it's made of), or, 21 cm

                             breadth = 18-2+2 cm, or, 14 cm

                        and, height = 15-2+2 cm, or, 11 cm

• Now, let's find the volume by applying:

Capacity = Length× Breadth× Height

Now, let's put the values in each:

            = 21 cm× 14 cm× 11 cm (Cubic centimetre)

            = 3234 c.c. (ANS)

For VOLUME:

It's the same formulae, all we have to do is to put the given external values. Because those are the total measurements occupied by the box.

So,

Volume = Length× Breadth× Height

            = 25 cm× 18 cm× 15 cm

           = 6750 c.c. (ANS)

Hopefully, it will HELP you!!

Thank you EVERYONE, for EVERYTHING.
