Question

Find the volume of used to make a closed box of outer dimensions 65cm*45cm*35cm .the thickness of wood being 2.5 cm.all around .also find the capacity of the box. Solve

Answer 1

Answer:

Step-by-step explanation:

Volume = 65cm*45cm*35cm - 62.5*42.5*32.5

=102375-86328.125

=16046.875

Capacity of the box = 62.5*42.5*32.5=86328.125

Hope its correct<3

Answer 2

Answer:

capacity=59,400 cm³

volume=27,000cm³

Step-by-step explanation:

internal volume=  (60 - 2 * 2.5 cm)  X (45 - 2 * 2.5 cm) X (32 - 2 * 2.5 cm)

     = 55 cm X 40 cm X 27 cm

capacity of the box  = 59, 400 cm³

external volume of the box is=l×b×h

=60 cm×45 cm×35 cm=86,400 cm³

volume of wood to make the box=

external volume-internal volume

hence by subtracting

86,400-59,400=27,000 cm³
