Question

Find the lateral surface area of the Hermika, if the side of cubical part is 8 m. (1M) (a) 128 m2 (b) 256 m2 © 512 m2 (d) 1024 m2​

Answer 1

Answer:

Option (c) 512 m2

Step-by-step explanation:

Given, lateral surface area of a cube = 256 m².

We know, lateral surface area of cube = 4( edge)².

Feedback

.. 4(edge)² = 256

256 4 → (edge)² =

(edge)² = 64

edge = 8.

Also, volume of cube = (edge)³.

... Volume of cube = (8)³ = 512 m³.

Answer 2

Step-by-step explanation:

Answer

:. Lateral Surface are aof cube = 4a²

L.S.A = 4(8)²

= 256 m²
