A 15 cm by 12 cm by 7 cm cuboid has how many faces, edges, and vertices?
Show answer and reasoning
Count six rectangular faces, twelve meeting segments and eight corner points.
A cuboid measures 2 cm by 5 cm by 3 cm. List the dimensions of its six faces, including repeated face sizes.
Show answer and reasoning
Opposite faces come in matching pairs, so there are two of each of the three face sizes.
A cuboid has side lengths 7 cm, 6 cm and 7 cm. Find the combined length of all twelve edges.
Show answer and reasoning
There are four of each dimension. Total = 4×(7+6+7)=80 cm.
A 4 cm by 6 cm by 13 cm cuboid has how many faces, edges, and vertices?
Show answer and reasoning
Count six rectangular faces, twelve meeting segments and eight corner points.
A cuboid measures 3 cm by 2 cm by 4 cm. List the dimensions of its six faces, including repeated face sizes.
Show answer and reasoning
Opposite faces come in matching pairs, so there are two of each of the three face sizes.
A cuboid has side lengths 4 cm, 6 cm and 9 cm. Find the combined length of all twelve edges.
Show answer and reasoning
There are four of each dimension. Total = 4×(4+6+9)=76 cm.
