Question

find the volume , total surface area and length of the diagonal of a cube whose edge is 1.2m​

Answer 1

Answer:

Step-by-step explanation:

Edge =1.2 m

First we find volume

:volume of cube = a³

(1.2)³m = 1.728

Then, we have to find total surface area

:Total surface area = 6(a)²

= 6(1.2)²

= 6(1.44)²m

= 8.64m²

Now.,we have to find diagonal of cube edge = 1.2m

: diagonal of cube = √3 a

= √3 ×1.2

= 1.2√3

= 2.08
