Answer:

To get the surface area of the rectangular box 5 cm long, 3 cm wide and 4 cm high, we will use the Surface Area formula of rectangular box. The Surface Area formula to be used is expressed below:

To get the surface area of the rectangular box 5 cm long, 3 cm wide and 4 cm high, we will use the Surface Area formula of rectangular box. The Surface Area formula to be used is expressed below:SA = 2 (WL + HL + HW)SA=2(WL+HL+HW)

To get the surface area of the rectangular box 5 cm long, 3 cm wide and 4 cm high, we will use the Surface Area formula of rectangular box. The Surface Area formula to be used is expressed below:SA = 2 (WL + HL + HW)SA=2(WL+HL+HW)where:

To get the surface area of the rectangular box 5 cm long, 3 cm wide and 4 cm high, we will use the Surface Area formula of rectangular box. The Surface Area formula to be used is expressed below:SA = 2 (WL + HL + HW)SA=2(WL+HL+HW)where:W = WidthH = HeightL = Length

W = 3 cm

W = 3 cmH = 4 cm

W = 3 cmH = 4 cmStep 2: Let's use the given to substitute on the formula:

W = 3 cmH = 4 cmStep 2: Let's use the given to substitute on the formula:SA = 2 (WL + HL + HW)

W = 3 cmH = 4 cmStep 2: Let's use the given to substitute on the formula:SA = 2 (WL + HL + HW)SA = 2 ((3 cm x 5 cm) + (4 cm x 5 cm) + (4 cm x 3 cm))

W = 3 cmH = 4 cmStep 2: Let's use the given to substitute on the formula:SA = 2 (WL + HL + HW)SA = 2 ((3 cm x 5 cm) + (4 cm x 5 cm) + (4 cm x 3 cm))SA = 2 (15 cm² + 20 cm² + 12 cm²)

W = 3 cmH = 4 cmStep 2: Let's use the given to substitute on the formula:SA = 2 (WL + HL + HW)SA = 2 ((3 cm x 5 cm) + (4 cm x 5 cm) + (4 cm x 3 cm))SA = 2 (15 cm² + 20 cm² + 12 cm²)SA = 2 (47 cm²)

W = 3 cmH = 4 cmStep 2: Let's use the given to substitute on the formula:SA = 2 (WL + HL + HW)SA = 2 ((3 cm x 5 cm) + (4 cm x 5 cm) + (4 cm x 3 cm))SA = 2 (15 cm² + 20 cm² + 12 cm²)SA = 2 (47 cm²)SA = 94 cm²

W = 3 cmH = 4 cmStep 2: Let's use the given to substitute on the formula:SA = 2 (WL + HL + HW)SA = 2 ((3 cm x 5 cm) + (4 cm x 5 cm) + (4 cm x 3 cm))SA = 2 (15 cm² + 20 cm² + 12 cm²)SA = 2 (47 cm²)SA = 94 cm²Answer:

W = 3 cmH = 4 cmStep 2: Let's use the given to substitute on the formula:SA = 2 (WL + HL + HW)SA = 2 ((3 cm x 5 cm) + (4 cm x 5 cm) + (4 cm x 3 cm))SA = 2 (15 cm² + 20 cm² + 12 cm²)SA = 2 (47 cm²)SA = 94 cm²
