### 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

### 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

### 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

### 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

### 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

### 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

### 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

### 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

### 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

### 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
