3. Triangular Pyramid
Option D. 649 cm² is the correct option.
Since surface area of a rectangular prism is calculated by the formula
Surface area = 2(length×width + width×height + length×height)
= 2(8×13 + 13×10.5 + 8×10.5)
= 2(104 + 136.5 + 84)
= 649 cm²
Therefore, Option D. 649 cm² is the correct option.
B is the area of the base so...you find the area of the base... Sorry that's all i really know about it!!
The base area is 30
the question is only for the Base (=area of triangle that is the base of the figure)
A=1/2 bxh b=5 h=12
The base would be 3 because 2*3/2=3
2 being the height, 3 being the width, and in the end 3 is also the base
there is no b volume in this answer
Your answer would be 649cm2 given the dimensions
The solution: A=2(wl+hl+hw)=2·(13·8+10.5·8+10.5·13)=649cm²
Since there are TWO of those faces, we get the total and multiply it by 2.
Total = 324.50 sq cm * 2
TOTAL AREA = 649 sq cm
the answer is d
