Question

A rectangular block
is formed by joining
together 24 cubes,
each with 1 cm
edges. If for the
rectangular block,
the perimeter of the
base is 16 cm, find
the height (in cm).
(All the sides of the
rectangular block
are more than 1 cm.)​

Answer 1

Answer:

height=2cm

Step-by-step explanation:

perimeter of rectangle=2(l+b)

perimeter of given rectangle=16cm

so 16cm=2(l+b)

16cm/2=(l+b)

8cm=(l+b)

1. (1,7)
2. (2,6)
3. (3,5)

above are length and breadth any of above can be length and breadth

so let we take (2+6 ) as length and breadth

2(2+6)=16 in perimeter we four corners we count two sides of same cubes so we have to seperate that 4 sides

so there will be 12 cubes +12 cubes above so height is 2 cms
