1.2.1) Calculate the radius of the cylindrical magic cube if the diameter is 67 mm.
Step 1: Recall the relationship between diameter and radius.
The radius is half of the diameter.
Radius=2Diameter
Step 2: Substitute the given diameter and calculate the radius.
Radius=267mm
Radius=33.5mm
The radius of the cylindrical magic cube is 33.5mm.
1.2.2) Calculate the total volume of the cylindrical magic cube in mm3.
The following formula may be used:
Volume of cylinder = π×radius×radius×height, where π=3.142.
Step 1: Identify the given dimensions and π value.
From the image, the height of the cylindrical magic cube is 60 mm.
From 1.2.1, the radius is 33.5 mm.
The value of π is given as 3.142.
Step 2: Substitute the values into the volume formula.
Volume=π×radius2×height
Volume=3.142×(33.5mm)2×60mm
Volume=3.142×1122.25mm2×60mm
Volume=3.142×67335mm3
Volume=211516.47mm3
The total volume of the cylindrical magic cube is 211516.47mm3.
1.2.3) Calculate the total surface area of the magic cube in mm2.
The following formula may be used:
Total surface area = side × side × 6
Step 1: Identify the side length of the cubic magic cube.
From the image, the side length of the cubic magic cube is 57 mm.
Step 2: Substitute the side length into the surface area formula.
Totalsurfacearea=side2×6
Totalsurfacearea=(57mm)2×6
Totalsurfacearea=3249mm2×6
Totalsurfacearea=19494mm2
The total surface area of the magic cube is 19494mm2.
