Answer:
A=360in^2
Step-by-step explanation:
there are 5 faces, 2 triangular, 3 rectangular
Triangular:
A=(9 * 10)/2=45
Since there are 2 of them the total is 90 in^2 for the triangles
Rectangular:
A=10*9=90
Since there are 3 the total is 270in^2
Total surface area is A=270+90=360in^2
Answer:I think the answer is letter B.
Step-by-step explanation:
A rectangle, is a quadrilateral with all angles at 90°.
a square is a quadrilateral with all equal sides, and right-angles all around.
now, the rectangle as well as the square, have all right-angles, the only difference is that the square has all equal-length sides, whilst a rectangle can have pairs of sides that vary in length.
The answer is 6. hope this helps
