Mutliplying decimals with numbers
Lets do the following multiplication
25
x419
9x25 = 2 2 5
1 x 25 = 2 5 0
4 X25 = 100 0 0 ...... add colums from top to bottom
= 1 0 4 7 5
for a decimal , just add a dot . or comma after 104 , this will be 104.75
so 25 x 4.19 = 104.75
Answer:
1800 m²
Step-by-step explanation:
The surface area of a prism is the sum of the areas of its faces.
⇒ Surface area of rectangle prism = 2(LH) + 2(BH) + 2(LB)
⇒ Surface area of rectangle prism = 2(LH) + 2(BH) + 2(LB) = 450 m²
⇒ 2(LH + BH + LB) = 450 m²
<u>Finding the surface area if the dimensions are doubled:</u>
⇒ 2[(2L × 2H) + (2B × 2H) + (2L × 2B)]
⇒ 2[(4LH) + (4BH) + (4LB)]
⇒ 2[4LH + 4BH + 4LB]
⇒ 2[4(LH + BH + LB)]
⇒ 2[2 × 2(LH + BH + LB)]
⇒ 2[2(450)] [2(LH + BH + LB) = 450 m²]
⇒ 2[900]
⇒ 1800 m² (Option C)
