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

<em>There's no need to check for (e)</em>

<em>Option b and d answers the question</em>

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
