Choose the two rectangular prisms that have a volume of 36 cm”.

Lina20 [59]

Answer:

B & D

Step-by-step explanation:

Volume is calculated as:

$Volume = Length * Width * Height$

For (a):

$Length = 3cm$

$Width = 4cm$

$Height = 5cm$

$Volume = 3cm * 4cm * 5cm$

$Volume = 60cm^3$

For (b):

$Length = 3cm$

$Width = 4cm$

$Height = 3cm$

$Volume = 3cm * 4cm * 3cm$

$Volume = 36cm^3$

For (c):

$Length = 4cm$

$Width = 2cm$

$Height = 2cm$

$Volume = 4cm * 2cm * 2cm$

$Volume = 16cm^3$

For (d):

$Length = 2cm$

$Width = 3cm$

$Height = 6cm$

$Volume = 2cm * 3cm * 6cm$

$Volume = 36cm^3$

There's no need to check for (e)

P[20,7)R(-4,-9)0(20,-9)S(-4,-24)What is the total length of the path from P to S?a.47 unitsb.55 unitsc.65 unitsd.73 units

rosijanka [135]

Given

The coordinates of the points on the path are:

P(20,7), R(-4,-9), O(20, -9), S(-4, -24)

The total length of the path from P to S is:

$=\text{ \mid PR\mid}+|RO|\text{ +}|OS|$

The distance d between two points can be found using the formula:

$d\text{ = }\sqrt{(x_2-x_1)^2\text{ +}(y_2\text{ -y}_1)^2\text{ }}$

The distance between P and R:

$\begin{gathered} |PR|\text{ = }\sqrt{(-4-20)^2\text{ +}(-9\text{ -7\rparen}^2} \\ =\text{ 28.84 units} \end{gathered}$

The distance between R and O:

$\begin{gathered} |RO|\text{ = }\sqrt{(20-(-4))^2\text{ + \lparen-9-\lparen-9\rparen\rparen}^2} \\ =\text{ 24 units} \end{gathered}$

The distance between O and S:

$undefined$
