aniked [119]

The percent error is 6.25%

Step-by-step explanation:

Percent error is given by:

Percent\ Error=\frac{|Experimental\ Value -\ Accepted\ value|}{Accepted\ value}*100

Here,

Accepted value = 80.0°C

Experimental Value = 75.0°C

Putting the values in the formula

Percent\ Error=\frac{|80.0 -75.0}{80.0}*100\\=\frac{|5.0|}{80.0}*100\\=\frac{5.0}{80.0}*100\\=0.0625*100\\=6.25\%

Hence,

The percent error is 6.25%

The volume of cube A is 216 cubic inches. The length of each edge in cube B is 2 inches longer than the length of each edge in c
lord [1]

Answer: 296 cubic in.

Step-by-step explanation: Since we are talking about cubes, and you know the volume of a cube is lwh, we know l, w and h are all equal, meaning be can cube root the volume to find all side lengths. The cube root of 216 is 6, so if each side in cube B is 2 longer, then the lwh for B is 8*8*8, or 512. 512-216=296.
