Students can go through AP Board 8th Class Maths Notes Chapter 14 Surface Areas and Volume to understand and remember the concepts easily.

## AP State Board Syllabus 8th Class Maths Notes Chapter 14 Surface Areas and Volume

→ If l, b, h are-the dimensions of cuboid, then:

(i) its lateral surface area is 2h (l+ b)

(ii) its total surface area is 2 (lb + bh + hl)

(iii) its volume is l × b × h

→ Lateral surface area of a cube is 4a^{2}

→ Total surface area of a cube is 6a^{2}

→ Volume of a cube is side × side × side = a^{3}

→ 1 cm^{3} = 1 ml

→ 1 l = 1000 cm^{3}

→ 1 m^{3} = 1000000 cm^{3} = 1000 l = 1 kl (kilolitre)
