Answer:

18

Step-by-step explanation:

The interquartile range is the middle 50% of the data.

To find the interquartile range,  we must first find the lower and upper quartiles.

In this case, the lower quartile is 76.5, and the upper quartile is 94.5.

Subtracting 76.5 from 94.5 gives us the answer of 18.

Let me know if this helps!

Area of a rectangle is Width * Length

Apply this to each area the question asks for

AreaTop = 8cm * 4cm = 32cm^{2}

AreaBottom = the same, 32cm^{2}

AreaFront = 2cm * 4cm = 8cm^{2}

AreaBack = the same, 8cm^{2}

AreaLeftSide = 2cm * 8cm = 16cm^{2}

AreaRightSide = the same, 16cm^{2}

TotalSurfaceArea = 16 + 16 + 8 + 8 + 32 + 32 = 112cm^{2}
