Mensuration

Step 1: Identify the dimensions of the table top.
The "top measures" likely refer to the length and width of a rectangular table.
Length m.
Width m cm.

Step 2: Convert all dimensions to the same unit (meters) for area calculation in square meters.
Length m.
Width : .
So, .

Step 3: Calculate the area of the rectangular table top.
Area .
Calculation: So, .
Alternatively, : 1.
75 x 3 ----- 5.
25 The area is square meters.

Step 4: Compare with options.
This matches option (3).

Step 1: Recall the formula for the total surface area of a cube.
A cube has 6 equal square faces.
Let the side length of the cube be .
The area of one square face is .
The total surface area (TSA) of a cube is .

Step 2: Use the given surface area to find the side length .
Given TSA = 600 cm .
Since length must be positive, cm.

Step 3: Compare with the options.
The side of the cube is 10 cm.
This matches option (2).
