Answer:
9m^3
Step-by-step explanation:
Seperate the shape to two shapes. Two rectangles.
Volume of the bottom rectangle：3X2X1=6
Volume of the top rectangle：1X1.5X2=3
6+3=9
Answer:
990, C
Step-by-step explanation:
The formula for the surface area of the bottom cushion is
A = 2wl + 2lh + 2hw (w is width, l is length, h is height)
w = 18, l = 21, h = 3
A = 2(18)(21) + 2(21)(3) + 2(3)(18)
A = 2(378) + 2(63) + 2(54)
A = 756 + 126 + 108
A = 990 (C)
Answer:
b = 28
Step-by-step explanation:
131 + 21 + b = 180
152 + b = 180
b = 28

Answer:
1728/ 125
Step-by-step explanation:
The ratio of corresponding lengths of the figures = ratio of the square root of their areas.
So ratio of lengths = 12/5.
Now volume is 3 dimensional so the ratio is the cube of the lengths
= 12^3/5^3
= 1728/ 125.
