Question

Find the LSA, TSA and volume of a cube of side 2.5 m​

Answer 1

Answer:

Side of cube = 2.5 m

Volume = (side) ³

= (2.5)³

= 15.625 m³

TSA = 6 x (side) ²

= 6 x (2.5)²

= 6x6.25 = 37.5 m²

LSA = 4 x (side) ²

= 4 x (2.5)²

= 4 x 6.25 = 25 m²

Answer 2

$lateral \: surface \: area \: = 4 {a}^{2} \\ = 4 \times {2 .5}^{2} \: {m}^{2} \\ = 4 \times 6.25 \: {m}^{2} \\ = 25 \: {m}^{2} \\ total \: surface \: area \: = 6 {a}^{2} \\ = 6 \times {2.5}^{2} \: {m}^{2} \\ = 6 \times 6.25 \: {m}^{2} \\ = 37.5 \: {m}^{2} \: \\ volume = {a}^{3} \\ = {2.5}^{3} \: {m}^{3} \\ = 15.625 \: {m}^{3}$
