A rectangular prism has dimensions of 3 cm. by 5 cm. by 5 cm. What is its surface area?

Bogdan [553]

$\bf \textit{surface area of a rectangular prism}\\\\ SA=2Lw+2Lh+ 2wh~~ \begin{cases} L=length\\ w=width\\ h=height\\ \cline{1-1} L=3\\ w=5\\ h = 5 \end{cases} \\\\\\ SA=2(3\cdot 5)+2(3\cdot 5)+2(5\cdot 5)\implies SA=30+30+50\implies SA=110$

Answer:

Volume=Length×Width×Height

Step-by-step explanation:

A rectangular prism is a 3D figure with 6 rectangular faces. To find the volume of a rectangular prism, multiply its 3 dimensions: length × width × height. The volume is expressed in cubic units.

EXAMPLE:

Lets say the HEIGHT is 2mm. Lets say the WIDTH is 1mm. Lets say the LENGTH is 10mm.

L×W×H

10×1×2=20mm

20 Cubic mm

Answer:

AC is 6.5 cm

Step-by-step explanation:

From trigonometric ratios:

$\sin( \theta) = \frac{opposite}{hypotenuse} \\$

opposite » 3 cm

hypotenuse » AC

angle » 28°

$\sin(28 \degree) = \frac{3}{AC} \\ \\ AC = \frac{3}{ \sin(28 \degree) } \\ \\ AC = \frac{3}{0.46} \\ \\ AC = 6.5 \: cm$
