You need to be able to explain your answer to earn the points!
False. Only one pair of sides is parallel. In a parallelogram, both pairs of opposite sides must be parallel to each other.
Find the volume. Make sure to state correct units in your response.
120 cubic in.
Find the volume. Make sure to state correct units in your response.
Vbottom= 4 x 2 x 2 = 16 cu in
Vtop= 2 x 2 x 2 = 8 cu in
Vtotal= 16 + 8 = 24 cu in
OR
Vleft= 2 x 4 x 2 = 16 cu in
Vright= 2 x 2 x 2 = 8 cu in
Vtotal= 16 + 8 =24 cu in

3 x 2 x 10
15 x 1 x 4
20 x 3 x 1
12 x 1 x 5
60 x 1 x 1

Vtotal=112 cu cm
Someone started packing boxes with toys in a shipping carton. If each box is one 1 ft3 (1 cubic foot), find the volume of the whole carton.
Area of base= 8 sq ft
Height of carton = 3 ft
Volume = 8 x 3=24 cu ft
Ghassan said this is an acute triangle. Tell if that is a correct label and how you know.
Correct. Angles are less than 90 degrees.
Which name: quadrilateral, polygon, parallelogram, rhombus, or rectangle, does NOT describe the shape below? Explain why not.
Rectangle- The shape is a rhombus. It is not a rectangle because it does not have four right angles.
The two prisms below both use cubic centimeters. Tell how the volumes compare (<, >, =) and how you know.
Prism A
Prism B
Prism A's volume is greater (60 cu cm) than Prism B's volume (54 cu cm).
