Answer:
Volume of a brick = 0.00975 m³.
Step-by-step explanation:
Volume of the wall = 63 m³
Cost to build the wall = 84000 Rs
Cost to prepare a brick = 13 Rs
Since, relation between cost of the wall is directly proportional to the volume of the wall
C ∝ V
C = kV
Here, k = Proportionality constant
k = = Constant
Therefore,
V₂ =
= 0.00975 m³
Therefore, volume of a brick is 0.00975 m³.

Answer:
(√2)x/2 or (√2/2)x
Step-by-step explanation:
Let's draw two squares, one with diagonal length x and the other with diagonal length √2. In the second case, the side length is 1, which you can confirm by recalling that 1^2 + 1^2 = 2*1^2 and √2*1^2 = √2.
These two squares are similar, even if they're of different sizes.
Writing an equation of ratios, we get:
side length 1
---------------------- = -------------
x √2
Then (side length)*√2 = x (after cross-multiplication)
and so (side length) = x/√2 or (√2)x/2 or (√2/2)x
This answer is already to the nearest tenth. The 5 is in the tenth's place.
