Answer:
T.S.A. of cube=243/8m²=30.375m²
L.S.A. of cube=81/4m²=20.25m²
Volume of cube=729/64m³=11.39m³
Step-by-step explanation:
T.S.A. of cube
=6a²
=6(2¼)²
=6(9/4)²
=6×81/16
=3×81/8
=243/8m²
=30.375m²
L.S.A. of cube
=4a²
=4(2¼)²
=4(9/4)²
=4×81/16
=81/4m²
=20.25m²
Volume of cube
=a³
=(2¼)³
=(9/4)³
=729/64m³
=11.39m³
