The net of the toy box would consist of 6 rectangles: one for the top, one for the bottom, and four for the sides.
To calculate the surface area of the toy box, we need to find the area of each individual rectangle in the net.
The dimensions of the rectangular prism are given as follows:
Length = 14 cm
Width = 10 cm
Height = 9 cm
The area of each rectangle can be calculated as follows:
Top and bottom rectangles: Length x Width = 14 cm x 10 cm = 140 cm^2 (each)
Side rectangles: Length x Height = 14 cm x 9 cm = 126 cm^2 (each)
Therefore, the total surface area of the toy box can be calculated by adding all the areas of the rectangles:
Total surface area = 2(140 cm^2) + 4(126 cm^2) = 280 cm^2 + 504 cm^2 = 784 cm^2
So, the surface area of the toy box is 784 cm^2.
Alexander built a toy box in the shape of a rectangular prism with an open top. The diagram below shows the toy box and a net of the toy box. 9 cm 10 cm 14 cm
