Answer : A
Explanation
Step 1:
Area of triangle base A = 10×10 × $\frac{1.73}{4}$ = 43.25 sq cm; height of prism h = 14 cm
Step 2:
Surface area of triangular prism = 2A + (a+b+c)h
= 2 × 43.25 + 30 × 14
= 506.5 square cm
Answer : B
Explanation
Step 1:
Area of triangle base A = $\sqrt{s\left ( s-a \right )\left ( s-b \right )\left ( s-c \right )}$
= $\sqrt{9.8\left ( 9.8-3 \right )\left ( 9.8 -9\right )\left ( 9.8-7.6 \right ) }$
= 10.83 sq in; height of prism h = 4.9 in
Step 2:
Surface area of triangular prism = 2A + (a+b+c)h
= 2 × 10.83 + (3+9+7.6) × 4.9
= 117.7 square in
Answer : D
Explanation
Step 1:
Area of triangle base A = 11.62 sq cm; height of prism h = 4.3 cm
Step 2:
Surface area of triangular prism = 2A + (a+b+c)h
= 2 × 11.62 + (8.3+8.7+2.8) × 4.3
= 108.37 square cm
Answer : C
Explanation
Step 1:
Area of triangle base A = 17.34 sq ft; height of prism h = 3.3 ft
Step 2:
Surface area of triangular prism = 2A + (a+b+c)h
= 2 × 17.34 + (6.8+8.5+5.1) × 3.3
= 102 square ft
Answer : B
Explanation
Step 1:
Area of triangle base A = 11.38 sq mi; height of prism h = 5.3 mi
Step 2:
Surface area of triangular prism = 2A + (a+b+c)h
= 2 × 11.38 + (6.9+3.4+8.4) × 5.3
= 121.87 square mi
Answer : A
Explanation
Step 1:
Area of triangle base A = 10.14 sq ft; height of prism h = 2.4 ft
Step 2:
Surface area of triangular prism = 2A + (a+b+c)
= 2 × 10.14 + (5.2+3.9+6.5) × 2.4
= 57.72 square ft
Answer : D
Explanation
Step 1:
Area of triangle base A = 7.45 sq in; height of prism h = 2.2 in
Step 2:
Surface area of triangular prism = 2A + (a+b+c)h
= 2 × 7.45 + (2.3+6.5+6.7) × 2.2
= 48.99 square in
Answer : C
Explanation
Step 1:
Area of triangle base A = 4.25 sq cm; height of prism h = 1.8 cm
Step 2:
Surface area of triangular prism = 2A + (a+b+c)h
= 2 × 4.25 + (2.5 + 3.4 + 4.3) × 1.8
= 26.85 square cm
Answer : A
Explanation
Step 1:
Area of triangle base A = 3.84 sq yd; height of prism h = 4.3 yd
Step 2:
Surface area of triangular prism = 2A + (a+b+c)h
= 2 × 3.84 + (2.4 + 3.2 + 4) × 4.3
= 48.96 square yd
Answer : B
Explanation
Step 1:
Area of triangle base A = 10.1sq m ; height of prism h = 4.1 m
Step 2:
Surface area of triangular prism = 2A + (a+b+c)h
= 2 × 10.1 + (4.3 + 5.4 + 8.4) × 4.1
= 94.41 square m
