Answer:
264 I believe
Step-by-step explanation:
We know that
surface area=area of the base+4*[area of one lateral triangle side]
area of the base=b²
b is the side length of the square
b=14 cm
area of the base=14²-----> 196 cm²
area of one lateral triangle side=b*h/2
b is the side length of the square
b=14 cm
h is the height of the lateral triangle side
h is equal to the slant height
h=15 cm
area of one lateral triangle side=14*15/2----> 105 cm²
surface area=196+4*[105]------> 616 cm²
the answer is
the surface area is 616 cm²
The answer is 5x because when you do the math 12 subtracted by 7 equals 5 then you add the x at the end.
To simplify that expression you'll join like terms.
8x + 4 - 5
8x - 1
