Find the total surface area of these solids

4 0
<h2>Step-by-step explanation:</h2><h3>We firstly find the surface area of only one face of the cube:</h3><h3>Sa=a²</h3><h3>Sa=1.2²cm</h3><h3>Sa=1.44cm²</h3>

<h2>Since the cube has 6 faces we multiply the surface area of one face(144cm²) with 6</h2>

Area(cube)=1.44cm²*6

=8.64cm²

<h2>Same thing with the prism but we have to find the area of one of his triangle face and rectangle face</h2>

S(triangle)=5mm*4mm*1/2

=10mm²

S(rectangle)=7mm*5mm=35mm²

<h2>The prism has 2 triangle faces and three rectangle faces so we multiply the area by those numbers and then we add those together to get the final area</h2>

S=10mm²*2+35mm²*3

S=20+105

S=125mm²

The diagonals of rhombus fghj intersect at point k. if side gh is equal to 3x - 10 and side jh is equal to 6x - 19, find x
exis [7]
A rhombus is a square but turned so it looks like a diamond. This means all the sides are equal. With this information we can build an equation to solve for x.

3x - 10 = 6x - 19

1) Subtract 3x from both sides.

-10 = 3x - 19

2) Add 19 to both sides.

9 = 3x

3) Divide both sides by 3.

3 = x

x =3.

A sand box measures 10 feet long by 8 feet wide by 1 foot deep what area of land must be clearest
Andrei [34K]

Answer: 80 cubic feet

Step-by-step explanation:

Hello! Your question was not very clear, but I'm assuming you need to find the volume of the sandbox.

To find volume, you need to multiply height by width by length, which is h*l*w.

Height: 1 foot

Width: 8 feet

Length: 10 feet

V=8*10*1=80 cubic feet.

Can someone please explain this in a way my dumb brain would understand? WHY does 2 - (-8) = 10? Shouldn't it be decreasing to -
Veseljchak [2.6K]
Hey! The most intuitive way I've been explained the idea of subtracting negative numbers is in terms of debts. <em>Subtracting</em> a debt from your bank account has the effect of <em>adding </em>money to it. Imagine you had $10 in your account, but you owed $8 in debt; your current balance would show $2 in your account. If you <em>took away that debt</em>, though, you'd be back up to $10. If we imagine your funds as positive numbers and your debts as negative numbers, we could express taking away that debt as:

2 - (-8) = 10

Hope that makes a little more sense!
