Answer 2

Concept Introduction:

An indication of how much overall space an object's surface takes up is its surface area.

Given that, from a wooden cubical block of edge $7$ cm, the largest possible right cone is cut out whose base is on one of the faces of the cube.

To find, the total surface area of the block left

Solution:

According to the rule,

The volume of the cone = $1/3$ × 3.14 ×$3.5$² × $7 = 89.797$ cm³

So, the remaining surface area = π$r$ √ ($r$² $+ h$²$)$ = $86.05 + 38.48 = 124.53$ cm²

Final Answer:

The final answer is $124.53$ cm²
