The mass of the photo frame : = 549.12 g

<h3>Further explanation</h3>

Given

a photo frame

two 5.2 mm sheets = 0.52 cm

22 cm by 20 cm dimension

Required

the mass

Solution

The volume of one sheet = l x w x h

= 22 cm x 20 cm x 0.52 cm

= 228.8 cm³

Mass of one sheet :

= density x volume

= 1.2 g/cm³ x 228.8 cm³

= 274.56 g

So for two sheets of polycarbonate :

= 2 x  274.56 g

= 549.12 g
