An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
The dimensions of this cube are height (h) = 1, length (l) = 9, and width (w) = 8. What is the surface area?
| 148 | |
| 172 | |
| 48 | |
| 178 |
The surface area of a cube is (2 x length x width) + (2 x width x height) + (2 x length x height):
sa = 2lw + 2wh + 2lh
sa = (2 x 9 x 8) + (2 x 8 x 1) + (2 x 9 x 1)
sa = (144) + (16) + (18)
sa = 178
The dimensions of this trapezoid are a = 4, b = 3, c = 7, d = 2, and h = 3. What is the area?
| 20 | |
| 14 | |
| 7\(\frac{1}{2}\) | |
| 30 |
The area of a trapezoid is one-half the sum of the lengths of the parallel sides multiplied by the height:
a = ½(b + d)(h)
a = ½(3 + 2)(3)
a = ½(5)(3)
a = ½(15) = \( \frac{15}{2} \)
a = 7\(\frac{1}{2}\)
The dimensions of this cube are height (h) = 5, length (l) = 9, and width (w) = 6. What is the volume?
| 216 | |
| 28 | |
| 35 | |
| 270 |
The volume of a cube is height x length x width:
v = h x l x w
v = 5 x 9 x 6
v = 270
