Answer:

Total material needed = 9.5 square feet

Step-by-step explanation:

Dimensions of I = 2. 5feet x 1 feet

Area = 2.5 square feet

Dimensions of S :

Top part = 1 feet x 1 feet

Area of top part = 1 square feet

Bottom part = 1 feet x 2.5 feet

Area of bottom part = 2.5 square feet

Total Area of S = 2.5 + 1 = 3.5 square feet

Total material needed = Area of I + Area of S + Area of S

= 2.5 + 3.5 + 3.5

= 9.5 square feet.

Answer:

$f'(x) = \frac{2{x}^{2}}{ \sqrt[3]{( {x}^{3} - 8) } }$

Step-by-step explanation:

$f(x) = ( {x}^{3} - 8)^{ \frac{2}{3} } \\ \\ f'(x) = \frac{2}{3} ( {x}^{3} - 8)^{ \frac{2}{3} - 1 } (3 {x}^{2} - 0) \\ \\ f'(x) = \frac{2}{3} ( {x}^{3} - 8)^{ \frac{2 - 3}{3} } \times 3 {x}^{2} \\ \\ f'(x) = 2{x}^{2}( {x}^{3} - 8)^{ \frac{ - 1}{3} } \\ \\ f'(x) = \frac{2{x}^{2}}{( {x}^{3} - 8)^{ \frac{ 1}{3} } } \\ \\ \huge \red{ \boxed{ f'(x) = \frac{2{x}^{2}}{ \sqrt[3]{( {x}^{3} - 8) } } }}$
