The surface area of a rectangular prism is 2210 cm2. Two of the dimensions are 5 cm and 10 cm. Find the measure of the other dim

Vlad [161]

The surface area of a rectangular prism is 2210 cm^2 Then the other dimension is 70.3 cm

<h3><u>Solution:</u></h3>

Given that surface area of rectangular prism is 2210 square centimeter

Also given that two of dimensions are 5 cm and 10 cm

To find: other dimension

<em><u>The total surface area of the rectangular prism is gievn as:</u></em>

$\text {Total surface area }=2(lb+b h+h l)$

Where, "l" is the length and "b" is the breadth and "h" is the height

The given values are: l = 5cm and b = 10cm

On substituting the given values in formula we get,

$\begin{array}{l}{2210=2(l \times b+b \times h+h \times l)} \\\\ {2210=2(5 \times 10+10 \times h+h \times 5)} \\\\ {2210=2(50+10 h+5 h)} \\\\ {1105=50+15 h} \\\\ {1055=15 h} \\\\ {h=70.3}\end{array}$

Thus the other dimension is 70.3 cm

Answer:

x=119 and x=80

Step-by-step explanation: a triangle always equals to 180

x+61=180

x+61-61=180-61

x=119

x+100=180

x+100-100=180-100

x=80
