Answer 1

AnswEr:

★ Equal ★

Cube has equal length, breadth and height.

More to know:

• Cube: A solid body having six equal square sides.

Diagram:

$\setlength{\unitlength}{4mm}\begin{picture}(10,6)\thicklines\put(0,1){\line(0,1){10}}\put(0,1){\line(1,0){10}}\put(10,1){\line(0,1){10}}\put(0,11){\line(1,0){10}}\put(0,11){\line(1,1){5}}\put(10,11){\line(1,1){5}}\put(10,1){\line(1,1){5}}\put(0,1){\line(1,1){5}}\put(5,6){\line(1,0){10}}\put(5,6){\line(0,1){10}}\put(5,16){\line(1,0){10}}\put(15,6){\line(0,1){10}}\put(4.6,-0.5){\bf\large a}\put(13.5,3){\bf\large a}\put(-4,5.8){\bf\large a}\end{picture}$

here,

• a is the side of cube.

Some formula related to cube:

• Total surface area of cube = 6a²
• Curved surface area of cube = 4a²
• Volume of cube = a³

A body having unequal length, breadth and height is know as Cuboid.

Diagram:

$\setlength{\unitlength}{0.74 cm}\begin{picture}\thicklines\put(3.5,6.1){\sf b}\put(7.7,6.3){\sf l}\put(11.3,7.45){\sf h}\put(6,6){\line(1,0){5}}\put(6,9){\line(1,0){5}}\put(11,9){\line(0,-1){3}}\put(6,6){\line(0,1){3}}\put(4,7.3){\line(1,0){5}}\put(4,10.3){\line(1,0){5}}\put(9,10.3){\line(0,-1){3}}\put(4,7.3){\line(0,1){3}}\put(6,6){\line(-3,2){2}}\put(6,9){\line(-3,2){2}}\put(11,9){\line(-3,2){2}}\put(11,6){\line(-3,2){2}}\end{picture}$

here,

• l = length of Cuboid
• b = breadth of Cuboid
• h = height of Cuboid

Some formula related to cuboid:

• Total surface area of Cuboid = 2(lb + bh + hl)
• Curved surface area of Cuboid = 2(l + b)h
• Volume of Cuboid = l × b × h
