Tino can finish a painting job in 2 hours. Dev can finish the same job in 8 hours. How
Mamont248 [21]

Answer:

5 hours

Step-by-step explanation:

First of all Dev is a lazy slacker if you ask me but alright. (8 hours to do the same project it takes Tino to do in 2 hours? what?)

But in all seriousness, lets go and solve this problemo:

because it will take half the amount of time with two people you must first add 8 and two to get 10 which you divide by 2 to get 5.

I hope I am correct, my scincerest apologies if not, have a great day.

The total surface area of this cuboid is 112cm squared find the value of x
soldier1979 [14.2K]

Answer:

x=2\sqrt{\frac{14}{3}}\ units  or  x=\frac{2}{3}\sqrt{42}\ units

Step-by-step explanation:

we know that

The surface area of a cube is equal to

SA=6x^{2}

where

x is the length side of a cube

In this problem we have

SA=112\ cm^{2}

substitute in the formula and solve for x

112=6x^{2}

x^{2}=112/6

square root both sides

x=\sqrt{\frac{112}{6}}\ units=2\sqrt{\frac{14}{3}}\ units=\frac{2}{3}\sqrt{42}\ units

Joel built a model town. He constructed three buildings that each had a volume of 18 cm cubed. Each building looked different. W
morpeh [17]

Answer:

The three buildings can look like following:

1. The building can look like a cube, with each side and height equal to 2.62 cm.

2. The building can look like a cuboid, with 3 cm length, 1 cm breadth and 6 cm height.

3. The building can look like a pyramid, with 3 cm length, 3 cm breadth and 6 cm height.

Step-by-step explanation:

The three possibilities of the appearance or shape of the building, with the volume equal to 18 cm³ are as follows:

1. CUBIC SHAPE:

The building can look like a cube with the length of each side and height given as:

Volume of Cube = 18 cm³ = L³

L = ∛18 cm³ = 2.62 cm

<u>Thus, the building can look like a cube, with each side and height equal to 2.62 cm.</u>

<u></u>

2. CUBOID SHAPE:

The building can also look like cuboid with the following dimensions.

Length = 3 cm

Breadth = 1 cm

Height = 6 cm

Thus, the volume becomes:

Volume of Cuboid = Length * Breadth * Height

Volume of Cuboid = 3 cm * 1 cm * 6 cm = 18 cm³

<u>Thus, the building can look like a cuboid, with 3 cm length, 1 cm breadth and 6 cm height.</u>

<u></u>

3. PYRAMID SHAPE:

The building can also look like pyramid with the following dimensions.

Length = 3 cm

Breadth = 3 cm

Height = 6 cm

Thus, the volume becomes:

Volume of Pyramid = (Length * Breadth * Height)/3

Volume of Cuboid = (3 cm * 3 cm * 6 cm)/3 = 18 cm³

<u>Thus, the building can look like a pyramid, with 3 cm length, 3 cm breadth and 6 cm height.</u>

<u></u>
