Question

Please answer my quickly!​

Answer 1

Explanation:

Both figures have the same heights.

Lateral surface area of cube  =4×side2=4×7×7=196 sq cm

lateral surface area of cylinder =2.πr.h=2×722×27×7=154 sq cm

So, a cube has a larger surface area.

Answer 2

Answer:

Hope it helps you

Explanation:

The given figure are alike in their heights. They differ as under :

(i) One is named cylinder and the other is a cube.

(ii) Cylinder is a solid obtained by revolving a rectangular lamina about one of its sides whereas cube is solid bounded by six squares.

(iii) Cylinder has two circular faces, whereas cube has six faces.

Given,

r = \frac { 7 }{ 2 } cm, h = 7 cm =\left( 2\times \frac { 22 }{ 7 } \times \frac { 7 }{ 22 } \times 7 \right) cm2 = 154 cm2

Lateral surface area of cylinder = 2πrh and, lateral surface area of cube

= Perimeter of base x height = (4 x 7 x 7) cm2 = 196 cm2

Clearly, cube has larger lateral surface area.
