Answer:

$h=12.5\ in$

Step-by-step explanation:

we know that

The surface area of a square prism is given by the formula

$SA=2(b^2)+4bh$

where

b is the length side of the square base

h is the height of the prism

we have

$b=5\ in\\SA=300\ in^2$

substitute

$300=2(5^2)+4(5)h$

solve for h

$300=50+20h\\20h=300-50\\20h=250\\h=12.5\ in$

Hello! Could someone help me with integral, please?

Oksana_A [137]

$\displaystyle \int \ln(x)dx\implies \int 1\cdot \ln(x)dx \\\\[-0.35em] ~\dotfill\\\\ \displaystyle u=\ln(x)\implies \cfrac{du}{dx}=\cfrac{1}{x}\hspace{5em}v=\int 1\cdot dx\implies v=x \\\\[-0.35em] ~\dotfill\\\\ \displaystyle \int \ln(x)dx\implies x\ln(x)-\int\cfrac{1}{x}\cdot x\implies x\ln(x)-x+C \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \left. \cfrac{}{}x\ln(x)-x \right]_{2}^{8}\implies [8\ln(8)-8] -[2\ln(2)-2]\implies 8\ln(8)-2\ln(2)-6$
