Answer:

Volume of cubiod= 108 in³
TSA of cubiod = 168 in²

Step-by-step explanation:

Given:

Dimensions of cubiod :

Length = 9 in.
Breadth = 6 in.
Height = 2 in.

To Find:

Volume and Total surface area

Solution:

We know that,

Volume of cubiod = Lbh

So,

→ Volume = 9 × 6 × 2

→ Volume = 54 × 2

→ Volume = 108 in³

And,

TSA of cubiod = 2(lb + bh + hl)

Substituting the values, we get:

→ TSA = 2(9 × 6) + (6 × 2) + (9 × 2)

→ TSA = 2(54 + 12 + 18)

→ TSA = 2 × 84

→ TSA = 168 in²

Hence,

Volume of cubiod= 108 in³
TSA of cubiod = 168 in²

If a 5 meter long metal bar has 40 kg mass then what is the mass of a metal bar 3 meters long

hjlf

24 kg

Step-by-step explanation:

You start by calculating the linear mass density of the rod:

d = m/L = (40 kg)/(5 m) = 8 kg/m

So for a 3-m long bar, the mass can be calculated as follows:

m = d×L = (8 kg/m)(3 m) = 24 kg

Answer:

x=3.89

Step-by-step explanation:

I'll go in depth for you.

Before we figure out what we do, let understand what we know about this triangle.

We know that both triangles have a angle that measure 27°.
We also know EH=5
FG=9
ZG=7
We need to know how to find EZ

Notice how line EG and HF intersect at Angle Z. We know that if two lines intersect at an angle, it form angles called vertical angles. This means that the two angles that are vertical to each other are congruent.

This means that angle Z in both triangles both measure the same.

Now since both triangles have 2 congruent corresponding angles, we can say that the Triangles are Similar due to the Angle-Angle Postulate.

"If two corresponding angles of two triangles are congruent, then the two triangles are similar."

What is mean when Triangles are similar? 

It means that the similar triangles corresponding angles are equal and their sides are in proportion.

The corresponding sides are 

EH and GF

EZ and ZG

HZ and HF.

Our proportion formula for similar triangles is 

Any two sides of the first triangle divided by each other must equal the two corresponding sides of the second triangles divided by each other respectively.
