Question

Find a total surface area and LSA of a cube with side 1.2cm

Answer 1

let,side of cube be a=1.2 cm
now,TSA=6a^2
=6×(1.2)^2
=6×1.44
=8.64 cm2
&LSA=4a^2
=4×(1.2)^2
=4×1.44
=5.76 cm2

Answer 2

Hello...
Answer...

Given that,

Edge of cube =1.2cm.

$T. S. A. \\ \\ = 6( {side)}^{2} \\ = 6 \times (1.2) \\ \\ = 6 \times 1.44 \\ \\ = 8.64 \\ \\ T. S. A. = 8. {64cm}^{2}$





$L. S. A. \\ \\ = 4( {sides)}^{2} \\ \\ = 4 \times (1.2) \\ \\ = 4 \times 1.44 \\ \\ = 5.76 \\ \\ L. S. A. = 5.76 {cm}^{2}$
Hope it helped ☺☺☺
