$\bf \stackrel{dividend}{\cfrac{9}{11}}\div \stackrel{divisor}{\cfrac{13}{33}}\implies \cfrac{9}{11}\cdot \cfrac{33}{13}\implies \cfrac{33}{11}\cdot \cfrac{9}{13}\implies \cfrac{3}{1}\cdot \cfrac{9}{13}\implies \boxed{\cfrac{27}{13}}\\\\
-------------------------------\\\\
\stackrel{divisor}{\cfrac{13}{33}}\cdot \boxed{\cfrac{27}{13}}\implies \cfrac{27}{33}\implies \cfrac{3\cdot 9}{3\cdot 11}\implies \cfrac{9}{11}$

Answer:

$\mathsf {SA = 112 in.^{2} }$

Step-by-step explanation:

$\textsf {Formula used :}\\\implies \textsf {SA = 2(length * width + width * height + length * height) }$

$\textsf {Given :}\\\textsf {Length = 5 in.}\\\textsf {Width = 4 in.}\\\textsf {Height = 4 in.}$

$\textsf {Solving :}$

$\implies \mathsf {SA = 2 (5 * 4 + 4 * 4 + 5 * 4)}$

$\implies \mathsf {SA = 2 (20 + 16 + 20)}$

$\implies \mathsf {SA = 2 (56)}$

$\implies \mathsf {SA = 112 in.^{2} }$

lawyer [7]

Answer:

$Volume = 150 yd^3$

$Surface Area = 150 yd^2$

Step-by-step explanation:

Going by the dimensions of the given three-dimensional figure, we can conclude that the figure is that of a cube. The height, length and width are equal.

Volume of a cube is given as $a^3$ , while surface area of a cube is given as $6a^2$

Where, a = the side length = 5 yards

$Volume = a^3 = 5^3$

$Volume = 150 yd^3$

$Surface Area = 6a^2 = 6(5)^2$

$Surface Area = 150 yd^2$
