Question

4.2

Answer 1

Answer:

The answer is "$\bold{1920 \ in^2}$".

Step-by-step explanation:

Please find the graph file.

Rectangular solid area:

Its region comprises four rectangles, each 15 for each case 14 in each.

The rectangle field is the formula $A = lw$

The four rectangles are therefore covered by a zone: $\to A = 4lw = 4 \times 15 \ in \times 14 \ in = 840 \ in^2.$

square Pyramids area:

The pyramids in both squares have 8 triangular facets.

Each triangle has a 15-inch basis with a 14-inch base.

The triangle zone formulation is $A = \frac{1}{2}bh$

That's it. The 8 triangles area is $\to A = 8 \times \frac{1}{2}bh = 4bh = 4 \times 15 \ in \times 18 \ in = 1080 \ in^2$

Total field surface:

Strong rectangular$= 840 \ in^2$

Pyramids in the Square$= 1080$

Overall area $= 1920 \ in^2$

The number is $1920\ in^2$ for a total area.
