Question

34. The volume of a cube is 13.824 m². The each of the cube is
of the cube is.
(a) 3.8 m
(b) 2.6 m
(c) 2.4 m
(d) 2.3 m
35. The volume of a cube whose surface area is 150
m² is:
(a) 124 m (b) 125 m
(c) 216 m (d) 343 m
​

Answer 1

VOLUME= l^3

where l is a side of cube

l^3= 13.824"m^3"

l = cuberoot of 13.824

=2.4m

surface area is 6l^2

where l is a side

6l^2=150

l^2=150/6

=> l= √25

=5m

volume= 125m^3

Answer 2

the correct answer is a.3.8

and the second one is

b.125
