Question

What length must cut off a rectangular marble slab 32 cm broad and 5 cm thick so that the volume of the cut off portion is 4 cu. dm​

Answer 1

Answer:

The length of the rectangular marble slab is 25cm.

Step-by-step explanation:

1 cubic decimeter is equal to 1000 cubic centimeter. So, the net volume of teh slab is 4000 cubic centimeters. Now, let the length be represented by a variable x.

                                                   32*5*x = 4000

                                                     160*x = 4000

                                                            x = 4000/160

                                                            x = 25 cm
