Step-by step explanation:
Answer:
no it is really easy question to answered so do it your self
PART A
Volume = Area of a triangle base x height (..or length)
Volume = 2,400cm^3
Volume = 1/2(16)(h)(20)
2,400cm^3=1/2(16)(h)(20)
2/400cm^3/160 = 160(h)/160
Part A= 15cm^3=height of the box
PART B
Surface Area = 1/2(15*16)(2)+20(17)(2)+16(20)
Surface Area = 240+680+320
Surface Area = 1,240
Part B = You will need approximately 1,240cm of cardboard.

Answer:
48
y
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = 
h (b₁ + b₂ )
where h is the height and b₁, b₂ the parallel bases , then
A = × 4
× (9x²y + 15x²y )
= 2 × 24x²y
= 48y
