Answer:
88 square inches
Step-by-step explanation:
The figure can be divided into two congruent trapezoids, each with bases 7 and 4 inches, and height 8 inches. Then the total area is ...
A = 2(1/2)(b1 +b2)h
A = (7 +4)(8) = 88 . . . . square inches
110.2
We can break the image into two by taking the cuboid and the triangular prism separately.
Volume of the cuboid= 3.5x7x3 = 73.5
Volume of prism= Area of triangle x3
i.e. 2(1/2 x 3.5x3.5) x3= 36.7
Add both the volumes = 73.5+36.7= 110.2
x = 8, --- 12
I hope this helped :))))))))))))))))))
the calculation is included. I hope its self explanatory
