The density of copper is 9.86 g/cm".
Work out the mass of the solid copper cuboid in kg.
10 cm
3 cm
5 cm

Answers

Answer 1

Answer:

volume of copper cuboid(V) =10cm×3cm×5cm=150cm³=150/10⁶ m³=1.5×10-⁴ m³

density of copper(d)=9.86×10-³+²=0.986 kg/m

we know,

mass=V/d=1.5×10-⁴/0.986=1.47×10-⁴ kg

Mrs. Patterson but a set of building blocks for her son each cube shaped block measured 4 cm on one side what is the volume of six building blocks

Answers

Given:

The shape of all building blocks is a cube of side 4 cm.

To find:

The volume of six building blocks.

Solution:

Volume of a cube is:

[tex]V=a^3[/tex]

Where, a is the side length of the cube.

Putting [tex]a=4[/tex], we get

[tex]V=(4)^3[/tex]

[tex]V=64[/tex]

It means the volume of each building block is 64 cubic cm.

Now, the volume of six building blocks is

[tex]Volume=6\times V[/tex]

[tex]Volume=6\times 64[/tex]

[tex]Volume=384[/tex]

Therefore, the volume of six building blocks is 384 cubic cm.

In a marketing survey involving 1,000 randomly chosen people, it is found that 630 use brand P, 420 use brand Q, and 210 use both brands. How many people in the survey use brand P and not brand Q?

Answers

By Set theory, 420 many people in the survey use brand P and not brand Q.

What is Set theory?

The mathematical concept of sets, which are well-defined collections of things that are referred to as their members or elements, is known as set theory. As only sets are the subject of pure set theory, the only sets that are taken into account are those whose members are also sets.

                               The major reason why set theory is significant is because it offers the axioms upon which the rest of mathematics is constructed. We study sets and their characteristics in the area of mathematical logic known as set theory. A collection of items or a group of items is referred to as a set. These items are frequently referred to as elements or members of a set.

P use = 630 people

Q use = 420 people

both P&Q use ie P∩Q = 210 People

use brand P but not brand Q = P/ P∩Q

                                               = 630 - 210

                                             = 420
