Answer : The correct answer is, $29\frac{62}{7}$

Step-by-step explanation :

The given expression is:

$10\frac{3}{7}+19\frac{5}{9}$

Step 1 : Convert mixed fraction into fraction.

$\frac{73}{7}+\frac{176}{9}$

Step 2 : Taking L.C.M

$\frac{(9\times 73)+(176\times 7)}{63}$

$\frac{(657)+(1232)}{63}$

$\frac{1889}{63}$

Step 3 : Convert fraction into mixed fraction.

$=29\frac{62}{7}$

Thus, the correct answer is, $29\frac{62}{7}$

45.44units^3

Step-by-step explanation:

Volume of the shaded part = Volume of the triangular based prism - Volume of square based prism

Volume of prism = Base area * Height

Volume of the triangular based prism = (5 * 4 * 5.7)/2

Volume of the triangular based prism = 57units^3

Volume of square based prism = 1.7* 1.7 * 4

Volume of square based prism = 11.56units^3

Taking the difference

Volume of the shaded solid = 57 - 11.56

Volume of the shaded solid = 45.44units^3
