Answer:
T. S. A of cube is 864cm²
Step-by-step explanation:
length of cuboid= 18cm
breadth of cuboid=4cm
height of cuboid=24cm
A. T. Q.
Vol cuboid= Vol Cube
L*B*H = a³ [let side of cube because]
18*4*24 = a³
1728 = a³
12 cm =a³
Now, T. S. A of cube =6*a²
=6*12*12
=864cm²

volume of rectangular metallic block = 18 × 4 × 24
= 1728 cm^2
volume of cube = volume of rectangular metallic block
volume of cube = side^3
side^3 = 1728cm^2
side = 3√1728
side = 12 cm
surface area = 6 side^2
= 6 × 12^2
= 6 × 144
= 864 m^2
