Question

Please help its in math

Answer 1

Answer:112inch^2

Explanation:

Total surface area =2(lw+hw+lh)

TSA=2(7*3+3.5*3+7*3.5)

TSA=112inch^2

Answer 2

112 square inches

Explanation:

The surface of the box is formed by 6 rectangles. Two of them have dimensions 7 by 3 inches, two have dimensions 7 by 3 1/2 inches, and two have dimensions 3 by 3 1/2 inches. Finding the area of all of these and adding them together, you get:

`2(7 \cdot 3) + 2(7\cdot 3(1)/(2)) + 2(3\cdot 3(1)/(2))=`

`2(21)+2(24(1)/(2))+2(10(1)/(2))=`

`42+49+21=112`

Hope this helps!
