The figure below is a net for a triangular prism. 14 m 10 m 10 m 18 m 12.81 m 12.81 m What is the surface area of the triangular prism, in square meters? Answer: A = m? %3D
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
**Dimensions:**
- Width of rectangle = 14 m
- Height of triangle attached to top side of rectangle = 10 m
- Base of triangle attached to top side of rectangle = 12.81 m
- Height of rectangle (main face) = 10 m
- Height of folded side (forming the side face of the prism) = 8 m
- Length of the triangular side (edges) corresponding to height of the rectangular prism = 12.81 m
