Question
A square plate of side 'x' cm is 4 mm thick. If its volume is 1440 cm3; find the value of 'x'.
Solution
Volume of the square plate = Volume of a cuboid
h = 4mm
= `(4)/(10)"cm"`
= 0.4cm
Volume of the square plate
= l x b x h
1440 = X x X x 0.4
1440 = x2 x 0.4
x2 = `(1440)/(0.4)` = 3600
x = `sqrt(3600)`
∴ x = 60cm.
