72 square units

Step-by-step explanation:

The area of the rectangle in the middle: 6x8 = 48 square units

The area of the triangle on the left: (5x6)/2 = 30/2 = 15 square units

The area of the triangle on the right: (3x6)/2 = 18/2 =9

(The 6 for the height of the triangle on the right is from the left side of the rectangle in the middle, they have to be the same length)

48+15+9 = 72 square units

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are

14

step-by-step explanation:

14 x 3 = 42
