Given : 5 identical cardboards, and out of those 5 card boards on 3 cardboard cover a red colour paper and on remaining two card board put a coloured tape all around it’s boundary.
To Find : the measure of tape and red paper which measure you need to calculate, perimeter or area
Solution:
red colour paper and coloured tape has to cover complete surface area of card board
Hence we need to find area
Area of one card board = A
Area of 3 card board = 3A
red colour paper = 3A
Area of 2 card board = 2A
colour tape = 2A
Area of card board A = 2( lb + bh + lh)
l = length , b = breadth , h = height
for cubical
Area of card board A = 6a²
a = side of card board
