with explain please​

Answer 1

Answer:

4735 $cm^{3}$

Step-by-step explanation:

The rectangular sheet is of 45cm x 35cm is cut at the corners as shown in figure 1 at the attachment.

Now the sheet is in the shape of figure 2 in the attachment.

It is made like an open box. To make it like an open box, the corners of the sheet which are remaining will be moved upwards. The box will be as in figure 3.

Now, The length of the box = 35 cm

        The width of the box = 25 cm

        The height of the box = 5 cm

Therefore, the volume of the box = length x width x height

                                                    = 35cm x 25cm x 5cm

                                                   = 4735 $cm^{3}$

The rectangular sheet is of 45cm x 35cm is cut at the corners as shown in figure 1 at the attachment.

Now the sheet is in the shape of figure 2 in the attachment.

It is made like an open box. To make it like an open box, the corners of the sheet which are remaining will be moved upwards. The box will be as in figure 3.

Now, The length of the box = 35 cm

The width of the box = 25 cm

The height of the box = 5 cm

Therefore, the volume of the box = length x width x height

= 35cm x 25cm x 5cm

= 4735 cm^{3}
