Given that l=20cm, b=12cm, h=9cm

∴T.S.A=2(lb+bh+lh)

=2[(20×12)+(12×9)+(20×9)]

=2(240+108+180)

=2×528

∴T.S.A=1056cm

Answer:

T.S.A. and L.S.A. of Cube are 2400 cm^2 and 1600 cm^2

Step-by-step explanation:

The surface area of a cube = 6a^2

(where a is the length of the side of each edge of the cube.)

= 6 × 20 × 20

= 2400 cm^2

L.S.A. (Lateral Surface Area) of Cube = 4a^2

= 4 × 20 × 20

= 1600 cm^2

Hope it helps you!
