A box open at the top has it's outer dimensions 10cm , 9cm and 2.5cm and its thickness is 0.5cm , find the volume of the metal
Answers
Answer:
64.50 cm³
Step-by-step explanation:
Volume of the Box = l × b × h
= 10 × 9 × 2.5
= 225.0 cm³
The Dimensions of the box without the thickness =
l = 10-0.5 = 9.5 b = 9-0.5 = 8.5 h = 2.5-0.5 = 2.0
Volume of the Box without the
Thickness of the Metal = 9.5 × 8.5 × 2.0
= 80.75 × 2
= 161.50 cm³
Volume of the Metal required
to make the Box of Metal = volume of the box - Volume of the box
without the metal covering
= 225.0 - 161.50
= 64.50 cm³
