Question

Find the volume and total surface area of a cube whose each edge is 2m 40cm

Answer 1

Step-by-step explanation:

the volume of cube = (edge)×(edge)×(edge)

so the volume = 2.40 × 2.40 × 2.40 mtr3

= 13.824 qubic mtr

surface area is the six time of edge square

means suface area =6 × (edge ) ×( edge )

so area = 6 × 2.40 × 2.40

=34.56 mtr2

Answer 2

GIVEN

EDGE 2M AND 40 CM

ACCORDING TO QUESTION

VOLUME OF CUBE =H*B*L

=200*40=8000CM(3)

HENCE VOLUME OF A CUBE IS 8000CM(3)
