Find the sum of the predecessor of the predecessor of 2987 and successor of the greatest 3 digits number is __________
grin007 [14]

Answer:

3985

Step-by-step explanation:

Note: predecessor means a number before for example  predecessor of 4 is 3. Similarly, successor is a number after for example the successor of 4 is 5.

The  predecessor of the predecessor of 2987  = 2987-2 = 2985

Let 2985 be x

The greatest 3 digit number = 999

And the successor of the greatest 3 digits number would be = 999+1 = 1000

let 1000 be y

We have find  the sum of x and y

= 2985+1000

= 3985

A surface area of a cube is related to its volume V by A = 6. V(2/3). If the volume of a
Luda [366]

The surface area of the cube is 64 cm².

<h3 /><h3>What is volume?</h3>

Volume is the amount of space that is enclosed within a container.

To calculate the surface area of the cube, we use the relation below.

Formula:

  • A = 6V{2/3}............ Equation 1

Where:

  • A = Surface area of the cube
  • V = Volume of the cube.

From the question,

Given:

  • V = 35 cm³

Substitute this value into equation 1

  • A = 6(35){2/3}
  • A = 6(10.6999)
  • A = 64.2
  • A = 64 cm²

Hence, The surface area of the cube is 64 cm².
