Answer:

$\text{Lateral surface area of container}=270\text{ cm}^2$

Step-by-step explanation:

Please find the attachment.

We have been given that a container is shaped like a triangle prism. Each base of container is an equilateral triangle with each side 6 cm. The height of container is 15 cm.

To find the lateral surface area of our given container we will use lateral surface area formula of triangular prism.

$\text{Lateral surface area of triangular prism}=(a+b+c)*h$ , where, a, b and c represent base sides of prism and h represents height of the prism.

Upon substituting our given values in above formula we will get,

$\text{Lateral surface area of container}=(\text{6 cm+ 6 cm+6 cm})*\text{15 cm}$

$\text{Lateral surface area of container}=\text{18 cm}*\text{15 cm}$

$\text{Lateral surface area of container}=270\text{ cm}^2$

Therefore, lateral surface area of our given container is 270 square cm.

Nitella [24]

Answer:

$\$ 268$

Step-by-step explanation:

Compound Interest: If P is initial amount, A is final amount, r is interest rate and n is number of years.

$A=P(1+\frac{r}{100})^n$

$Here\ P=\$ 200,\ r=5\%\ and\ n=6\ years\\\\We\ have\ to\ find\ out\ A\\\\A=200(1+\frac{5}{100})^6\\\\A=200(1+0.05)^6\\\\A=200(1.05)^6\\\\A=200\times 1.340095641\\\\A=268.02\\\\A\approx \$ 268$
