Answer:
<em>The surface area of square prism = 384 units squared</em>
Step-by-step explanation:
<u><em>Explanation</em></u>:-
<em>Given the square prism side 'a' = 8 units</em>
<em>The surface area of square prism = 2 a² + 4 a h</em>
Given square prism length , width and height also equal identical sides
The surface area of square prism = 2 a² + 4 a h
= 2(8)² + 4 (8)(8)
= 2(64) + 4(64)
= 384 units squared
<u><em>Final answer</em></u>:-
<em>The surface area of square prism = 384 units squared</em>
Sin (A + B) = sin A cos B + cos A Sin B
<span>Cos (A - B) = cos A cos B + sin A sin B </span>
<span>=> (SinACosB+ CosASinB) (CosACosB +SinASinB) </span>
<span>=>SinACosACos^2B+Sin^2ACosBSinB+Cos^2A... </span>
<span>=>SinACosA(Cos^2B+Sin^2B) +SinBCosB(Sin^2A+Cos^2A) </span>
<span>we know that Sin^2+Cos^2=1 </span>
<span>=>SinACosA(1)+SinBCosB(1) </span>
<span>=SinACosA+SinBCosB </span>
<span>Proved
</span>
Answer:
$10.8 is left.
Step-by-step explanation:
Given that,
Total amount = $54
Left amount = 20%
We need to find how much tip should you leave. It means we need to find 20% of 54. So,
So, $10.8 is left.
